Worksheet: Molar Concentrations

In this worksheet, we will practice calculating the molar concentration of a solution from the solvent volume and mass or moles of dissolved solute.

Q1:

Calculate the volume in L of a 0.125 M boric acid solution containing 0.500 mol of boric acid.

Q2:

During a titration, 22.4 mL of 0.100 MNaOH was required to neutralize the acidic analyte.

Calculate the number of moles of sodium hydroxide in the titer.

  • A0.224 mol
  • B 2 . 2 4 × 1 0 mol
  • C4.46 mol
  • D 4 . 4 6 × 1 0 mol
  • E2.24 mol

Calculate the number of grams of sodium hydroxide in the titer.

Q3:

A 600 mL solution contains 10.1 g of magnesium chloride. What is the molar concentration of magnesium chloride in this solution?

Q4:

1.0 liter of a sodium chloride solution contains 2.0 moles of sodium chloride. What is the concentration of sodium chloride?

Q5:

A 0.80-liter solution contains 0.40 moles of acetic acid. What is the molar concentration of acetic acid in this solution?

Q6:

Distilled white vinegar is a solution of acetic acid, CHCOH32, in water. A 0.500 L vinegar solution contains 25.2 g of acetic acid. What is the concentration of the acetic acid solution in units of molarity?

  • A0.210 M
  • B0.621 M
  • C1.19 M
  • D0.839 M
  • E0.938 M
