3. What is the equation for calculating weight/volume percent solutions?

a. M/V percent solution = Mass of solute (g) ÷ Volume of solution (mL) × 100

b. M/V percent solution = Mass of solute (g) × Volume of solution (mL) ÷ 100

c. M/V percent solution = Volume of solute (g) ÷ Mass of solution (mL) × 100

d. V/V percent solution = Volume of solute (mL) ÷ Volume of solution (mL) × 100
