15-4 Parts Per Million (PPM = mg/L) 1. LD50 is a designation for the level of dosage required to kill 50% of the test subjects - usually lab rats. If it takes only .063 grams of arsenic in a 1.0 liter volume to kill 50 % of a sample of test rats, what is the LD50 for arsenic in parts per million? (A: 63 ppm) 2.

Parts Per Million (ppm) Concentration Calculations. 1. 150mL of an aqueous sodium chloride solution contains 0.0045g NaCl. Calculate the concentration of NaCl in parts per million (ppm). ppm = mass solute (mg) ÷ volume solution (L) mass NaCl = 0.0045g = 0.0045 x 1000mg = 4.5mg volume solution = 150mL = 150 ÷ 1000 = 0.150L
