Question 9 • *25-26 KCS18 Chemistry IC
ppmv is calculated as (volume of solute ÷ volume of solution) × 1,000,000. In C, the solute’s volume can be found from its mass and density, and the solution volume is given. In D, the solute volume is given, while the solution volume can be found from its mass and density. Moles alone do not provide the solute’s volume, so A and B are insufficient.
