Considering the definition of molar mass, the number of moles of Ti and Fe₂O₃ are 0.087 moles and 0.11 moles respectively.

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

The molar mass of Ti is 204.37 g/mole.

You know the molar mass of the elements is:

So, the molar mass of the compound Fe₂O₃ is calculated as:

Fe₂O₃= 2× 55.85 g/mole + 3× 16 g/mole

Solving:

Fe₂O₃= 159.7 g/mole

You can apply the following rules of three:

moles of Ti= (17.8 grams× 1 mole)÷ 204.37 grams

moles of Ti= 0.087 moles

If by definition of molar mass 159.7 grams of Fe₂O₃ are contained in 1 mole, 17.8 grams of Fe₂O₃ are contained in how many moles of Fe₂O₃?

moles of Fe₂O₃= (17.8 grams× 1 mole)÷ 159.7 grams

moles of Fe₂O₃= 0.11 moles

Finally, the number of moles of Ti and Fe₂O₃ are 0.087 moles and 0.11 moles respectively.

The secondary cell wall of the elongated, hollow xylem cells, which are dead, contains lignin.

The specialized tissue in vascular plants called xylem distributes nutrients and water from the plant-soil contact to the stems and leaves as well as serving as a mechanical support system and a storage system. One of the key characteristics that sets vascular plants apart is the xylem's ability to transmit water.

Vascular bundles, which are found in both non-woody plants and non-woody sections of woody plants, contain xylem. In woody plants, a meristem known as the vascular cambium lays down secondary xylem. as a component in a starry arrangement rather than a bundle, as in many ferns.

Density of X = 0.5 g/cm³

Volume of Y = 5 cm³

Mass of Z = 20 g

As we know Density is the substance's mass per unit of volume. So according to the given values of X,Y and Z we can calculate density, mass and Volume.

For X:

Volume of X = 10g

Mass of X = 50cm³

Density =Mass ÷ Volume

Density = 10 /50

Density = 0.5 g/cm³

For Y  

Mass of Y = 50g

Density of Y = 10g/cm³

Volume = Mass / Density

Volume = 50 / 10

Volume = 5 cm³

The volume of X = 20.0 cm³

Then density of X = mass/ volume

Density of X         = 20/10

Density of X       = 2 g/ cm³

2) For Y

The mass of Y = 50gm

density of Y = 10 gm/cm³

volume  of Y = mass /density

Volume of Y = 50/10

The atomic mass of the element X is 56 and the element can be seen to be iron.

In this problem, we are given a compound to obtain the identity of the unknown element therein.

We already can relate that;

Number of moles = mass/molar mass

Number of moles Br  = 0.04806 moles

Molar mass of Br could be obtained as 79.9 g/mol

We have;

Mass = Number of moles x molar mass

         = 0.04806x 79.9

       = 3.84 g

Mass of X = 4.735 - 3.84

                 = 0.895 g

Given that there are 3 moles of Br for every 1 mole of X. We have 0.04806 mole of Br present in 4.735 g, then the number of moles of X present would be:

                              0.04806/3 = 0.01602 moles

Molar mass = mass/mole

                     = 0.895/0.01602

                          = 55.87 or 56 g/mol

Hexane, CH3CH2CH2CH2CH2CH3, has a boiling point of 69ºC, while butane has a boiling point of 0.4ºC. Both molecules are nonpolar. Describe the significant difference between these two substances' boiling points.

Intermolecular attractions are the likely cause of the significant disparity in the boiling points of butane and hexane. Due to its size (molecular weight = 86) and higher number of electrons and nuclei, hexane has stronger and more durable van der Waals forces. With a molecular weight of 58, butane is a smaller molecule with less van der Waals forces.

Hexane has a higher boiling point than butane as a result, while butane has a lower boiling point.

Since the temperature remains constant, you can use Boyle's Law to find the final volume:

P₁V₁ = P₂V₂

In this formula, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. Before, you can plug the given values into the equation and solve for "V₂", you need to convert mmHg to atm to maintain consistent units.

760 mmHg = 1 atm

P₁ = 3,450 mmHg / 760 mmHg = 4.54 atm      P₂ = 1.4 atm

V₁ = 11.2 L                                                            V₂ = ? L

P₁V₁ = P₂V₂                                                  <----- Boyle's Law

(4.54 atm)(11.2 L) = (1.4 atm)V₂                    <----- Insert values

50.848 = (1.4 atm)V₂                                   <----- Multiply 4.54 and 11.2

36 = V₂                                                        <----- Divide both sides by 1.4

The mass of a sample of copper with a volume of 4.5 cubic centimeters is 40.32 grams.

A substance's density is defined as its mass per unit of volume. Density is most frequently represented by the symbol, however Latin letter D may also be used. Mass divided by volume is the formula for density in mathematics: ρ = m / v , where ρ is the density, m is the mass, and V is the volume.

So, ρ = m/v

8.96 = m / 4.5

40.32 g = mass

Therefore if a patient receives a dose with an activity of 53. 8 mCi of technetium-99m for cardiac imaging, radioactivity will be left in the patient’s body 72 hours after injection is 0.00024

The equation that describes the radioactive decay is:

Ln [A] = -kt + Ln [A]₀

Where [A] could be taken as activity of the source after time t, [A]₀ is initial activity and k is decay constant.

Decay constant could be written as:

k = ln2 / Half-life

k = ln 2 / 6h

k = 0.115h⁻¹

Replacing in decay equation:

ln a = -0.115 x 72  + Ln [53.8]

ln a = - 8.28 + 3. 98
