Using molarity to find solute moles and solution volume

Question

Calculate the volume in liters of a 0.299/molL barium acetate solution that contains 475.mmol of barium acetate BaC2H3O22. Be sure your answer has the correct number of significant digits.

Answer 1

First we’ll convert 475 mmoles to moles

475 mmoles x 1 mol/1000 mmol = 0.475 mmoles

Next, we’ll determine the volume in liters

0.475 moles x 1 L/0.299 moles = 1.589 L

Finally, convert to mls and report to 3 significant digits

1.589 L x 1000 mls/L = 1589 mls = 1590 mls
