Question
Benzene is a carcinogenic (cancer-causing) compound. A benzene-contaminated water sample contains 3.1×10−5% benzene by mass.
What volume of the water in liters contains 225mg of benzene? (Assume that the density of the solution is 1.0 g/mL.)

Answers
(g solute/g solution)*100 = 3.1E-5
(0.225/g soln)*100 = 3.1E-5
Solve for g solution (in mL) and convert to L.
