Question

Calculate the mass percent (m/m) of a solution prepared by dissolving 41.98 g of NaCl in 151.7 g of H₂O

Express your answer to four significant figures.

Mass percent (m/m) =

Vinegar is a solution of acetic acid in water. If a 145 mL bottle of distilled vinegar contains 34.3 mL of acetic acid, what is the volume percent (v/v) of the solution?

Express your answer to three significant figures.

Volume percent (v/v) =

Calculate the mass/volume percent (m/v) of 19.5 g NaCl in 67.5 mL of solution.

Express your answer to three significant figures.

Mass/volume percent (m/v) =

Calculate the molarity (M) of 156.0 g of H₂SO₄ in 1.255 L of solution.

Express your answer to four significant figures.

Molarity =

Concentration is the amount of solute dissolved in a certain amount of solution:
amount of solute
concentration of a solution
amount of solution
Solution concentrations are usually given as one of the following:
• Mass percent (m/m)-the mass of the solute in grams for exactly 100 g of solution
• Volume percent (v/v)–the volume of solute in exactly 100 mL of solution
Mass/volume percent (m/v)-the mass of solute in grams for exactly 100 mL of solution
Molarity (M)-the number of moles of solute in exactly 1 L of solution
