Problem

A water sample contains the pollutant chlorobenzene with a concentration of 16 ppb (by mass). What volume of this water contains 5.01×10² mg of chlorobenzene? (Assume a density of 1.00 g/mL.)

Solution

We will solve this problem through these steps:

• Find grams of chlorobenzene
• Find the mass of solution using the ppb formula
• Find volume of solution using density

The formula for ppb is:
