a. You are preparing a gas standard by injecting 43mg of chloroform into 1L container. Calculate the concentration of chloroform in ppm. b. Mars' atmosphere is composed of 95.32% carbon diaxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the sarface is 6.35mbar which is over 100 times less Earth's. Temperature is 20C. L. Calculate the molecular weight of martian atmosphere II. Calculate the density of martian atmosphere AWs of Af =40g/mole;CO2=44g/ mole; O2=32g/mole;N2=28g/mole) a.
