- a) Calculate the molar mass of 118.8 g of an anesthetic gasthat occupies 13.46 L at temperature and pressure of 22°C and 1.08atm, respectively.
b) Chemical analysis showed that thegas contained C=12.1%, F=28.8%, Cl=18.2%, Br=40.4% and H=0.5%, bymass. Determine the chemical formula of the gas. Atomic weights:C=12, F=19, Cl=35.5, Br=80, H=1.
Calculate the molar mass of 6.7 g ofN2 (gas) – O2 (gas) mixture that occupies avolume of 5.6 L at 22°C temperature and pressure of 1 atm.Determine the ratio of N2 to O2 in the gasmixture. Atomic weights: N=14, O=16.
