Question

A 1025 mL1025 mL sample of drinking water was found to contain 33.0 mg33.0 mg of lead. Calculate the concentration of lead in milligrams per liter.

Answer 1

Answer #1

from the given data

1.025 L (1025 mL) contain 33.0 mg Pb

1.0 L contain 1.0 x 33 / 1.025 = 33.19 mg

answer = 33.19 mg/L
