The molar mass of NH4NO3 in g/mol is 80g/mol.
HOW TO CALCULATE MOLAR MASS:
The molar mass of a compound can be calculated by summing the atomic masses of its constituent elements.
In ammonium nitrate (NH4NO3), there are nitrogen, hydrogen, and oxygen elements.
Atomic mass of nitrogen = 14Atomic mass of oxygen = 16Atomic mass of hydrogen = 1Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)
Molar mass of NH4NO3 = 80g/mol

What mass of aluminum must react with 100 g of copper (ii) phosphate? (10g)
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
mole =given mass ÷ molar mass
2 Al + 3 Cu[tex]_3[/tex](PO[tex]_4[/tex])[tex]_2[/tex] → Al[tex]_2[/tex] (PO[tex]_4[/tex])[tex]_3[/tex]+ 3 Cu
moles of copper phosphate= 100 g/380.58
=0.26 moles
3 moles of copper sulphate need 2 mole of Al
0.26 moles of copper sulphate need (2/3)×0.26
=0.17moles
mass of Al= 0.17×26
=4.42g
Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

At room temperature Bromine is a liquid and lodine is a solid, what can be inferred
about the intermolecular forces of these two elements?
Answer:
Explanation:
The intermolecular forces are stronger in Iodine, meaning that its molecules are stronger and can hold that solid structure at room temperature, where Bromine cannot due to its IMF's being weaker.
At the end of seafloor spreading, where does the molten rock solidify?
Answer:
As the two plates move apart from each other, which often occurs at a rate of several centimetres per year, molten rock wells up from the underlying mantle into the gap between the diverging plates and solidifies into new oceanic crust. Spreading centres are found at the crests of oceanic ridges.

explain the electrolysis of MgCl2 in aqueous solution
During electrolysis, a current is passed through the molten MgCl2, and when this happens, the Mg2+ ions move to the negative electrode where they PICK UP OR GAIN ELECTRONS. This is reduction. The Cl- ions move to the positive electrode where they LOSE ELECTRONS. This is oxidation.

A student wants to test for the concentration of food dye FD&C Yellow #5 (Tartrazine) in a yellow Starburst candy. First, the student must prepare standard solutions for the calibration curve. The student has a stock solution of FD&C Yellow #5; the concentration is 0.1140 M. The student takes 6.50mL of the stock solution and dispenses it into a 50.0mL volumetric flask. The flask is then diluted to volume with water. What is the concentration of this standard solution?
The molarity of the diluted standard solution is obtained by calculation to be 0.015 M.
Recall the dilution formula;
C1V1 = C2V2
C1 = Initial concentration = 0.1140 M
V1 = initial volume = 6.50mL
C2 = Final concentration = ?
V2 = Final volume = 50.0mL
Making C2 the subject of the formula and substituting values;
C2 = C1V1/V2
C2 = 0.1140 M × 6.50mL/50.0mL
C2 = 0.015 M

Rebekah finds that a solution of sugar in water has a volume of 1. 32 fl. Oz. How should she report this amount using the metric system? (1 fl. Oz. = 29. 6 mL) 0. 403 m 1. 40 qt 37. 5 g 39. 1 mL.
Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.
The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.
The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.
Thus, the volume of sugar solution has been reported in mL.
The given sugar solution has volume of 1.32 fl. Oz
The volume in mL can be given as:
[tex]\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL[/tex]
The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.

Using the “rule of 8” explain why carbon is the backbone of organic molecules
Answer:
Carbon has 4 valence electrons (electrons that are used in bonding), and therefore it can make 4 bonds which is the most one can (other than some exceptions, but in general it is the most). It wants to make 4 bonds so it can reach a full octet of 8 elections, hence the rule of 8.
Explanation:
Answer:
I suggest you See Explanation. But tldr: Carbon forms four bonds with no lone pairs.
Explanation:
By "rule of 8" I am assuming you mean "Octet Rule." In case you don't know, the octet rule (or rule of 8) is a rule referring to the maximum number of valence shell electrons that an atom can hold: 8 electrons. However, there are exceptions to this: octet-deficient and expanded octet atoms. Octet-deficient atoms follow what is known as the duet rule (or rule of 2), as seen in the case of H and He, or have have a capacity of up to 6 electrons in their valence shell, as seen in the case of B and Be. Expanded octets contain 10, 12, or even 14 electrons and occur in Period 3 elements and after. (It was previously assumed that this was due to d-orbital hybridization but that hypothesis has been disproven and currently an explanation regarding expanded octets doesn't exist. Yet another Nobel Prize worthy concept to solve when you have free time!)
Anyways, how does this all apply to Carbon being the backbone of the millions of organic molecules? Well, carbon follows the octect rule. Unlike duet rule atoms, it is not limited to one bond with another atom. Neither does it hold many lone pairs to itself nor form over four bonds at once causing a decrease in stability. No, Carbon forms four bonds with no lone pairs and has perfect stability in terms of both formal charge and octect rule in many of its structures. Its capacity to bond to up to 4 atoms without comprimising stability is the reason why carbon is the backbone of organic molecules.
