f the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of H2O at a given temperature, how many grams of NaCl can be dissolved in 250.0 mL of H2O

Answers

Answer:

76.5 grams

Explanation:

Solubility of sodium chloride = [tex]\dfrac{30.6}{100}=0.306\ \text{g/mL}[/tex]

Now volume of water is 250 mL

We have to find the amount of NaCl that can be dissolved in the above mentioned amount of water

Let the mass of NaCl that can be dissolved be m so

[tex]\dfrac{m}{250}=0.306\\\Rightarrow m=250\times0.306\\\Rightarrow m=76.5\ \text{g}[/tex]

The mass of NaCl that can be dissolved is 76.5 grams.

a)chemical equations
b) stoichiometry
c) molar mass
d)coefficient​

Answers

Answer:

b) stoichiometry

Explanation:

Stoichiometry is the study of quantitative relationships between the amounts of reactants and products.

The word is coined from two Greek words; stoicheon  which means atom and metron which means measurement. It deals with chemical calculations based on the elementary particles of matter. Such calculations highlights the relationships between the composition or chemical reactions of matter and the mole.

calculate the percent by mass of 4.35g of Na I dissolved in 105g of water​

Answers

We are given:

Mass of Na added = 4.35 grams

Mass of water = 105 grams

Mass Percent of Na:

Total mass of the solution = mass of solute + mass of solvent

Total mass of the solution = 4.35 + 105 = 109.35 grams

Mass percent of solute = (mass of solute / mass of solution) * 100

Mass percent of Solute = (4.35 / 109.35) * 100

Mass percent = 3.978 %

4. Answer, Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.

5. Answer The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.

6.Answer is solid

Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

7. Answer Water behaves differently to most other substances because, in its solid state (ice), its particles are less densely packed than in its liquid state. This is why ice floats.

8. Answer 212 degrees F.

Sea Level: Water boils at 212 degrees F. and simmers at 190 degrees F.

9. Answer When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.

11.  Answer is Energy is consumed (endothermic) to melt ice (solid to liquid) so the opposite process (liquid to solid) must be exothermic.

12.In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.

ok alright. But where’s the question?
