Solution: 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: 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.)

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:
