WHAT WOULD HAPPEN TO CAFFEINE IF THE SUBLIMATION STEP WERE PERFORMED AT 760 MM OF HG?

A mixture of two gases (gas X and gas Z) is pumped into a sealed container half-way filled with 5.0 L of water. The total pressure of the gases over the water is 1.34 atm. If the pressure of gas Z is 0.52 atm. How many grams of gas X are in the water if the molar mass for gas X is 22.31 g/mol? The Henry's law constant for gas X is 0.0266 mol/(L-atm). 16. Grams of gas X:

If a gaseous mixture of He, Ne, and N2 has a pressure of 871 mm Hg, what is the partial pressure of N2, in mm Hg, if He and Ne have partial pressures of 775 mm Hg and 83 mm Hg, respectively?
