Expert Answer
a. Subject: Chemistry Topic: Concentration unitsTo calculate the concentration of chloroform in ppm, we need to know the mass of chloroform and the volume of the container in which it is dissolved. Given, mass of chloroform = 43 mg = 0.043 g Volume of container = 1 L = 1000 mL Concentration of chloroform in ppm = (mass of chloroform / volume of container) x 10^6 = (0.043 g / 1000 mL) x 10^6 = 43 ppm
