1.The total pressure of a mixture of O2(g) and H2(g) is 1.95 atm. The mixture is ignited and the resulting water is removed. The remaining mixture is pure H2(g) and exerts a pressure of 0.210atm when measured at the same temperature and volume as the original mixture. What were the mole fractions of O2(g) and H2(g) in the original mixture?

A bottling machine can be regulated so that it discharges an average of μ ounces per bottle. It has been observed that the amount of fill dispensed by the machine is normally distributed with σ = 1.0 ounce. If a sample of  n = 9 filled bottles is randomly selected from the output of the machine on a given day (all bottled with the same machine setting), and the ounces of fill are measured for each, then the probability that the...
