Calculate the volume of H2(g) at 273 K and 2.00 atm that will be formed when 275 mL of 0.725 M HCl solution reacts with excess Mg to give hydrogen gas and aqueous magnesium chloride. A gaseous compound is 30.4% nitrogen and 69.6% oxygen by mass. A 5.25-g sample of the gas occupies a volume of 1.00 L and exerts a pressure of 1.26 atm at -4.0°C. What is its molecular formula?

A soda manufacturing company is experimenting with changing the taste of its
product as the concentration of carbon dioxide changes. To track their results,
they must determine how concentration changes with pressure. The concentration
of CO2 under a partial pressure of 0.58 atm is 390.1 ppm. What is the
concentration (in ppm) of the CO2 when the partial pressure is 0.752 atm at the
same temperature?
Report your answer to the tenths place and do not include units.
The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.00056 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 4.0 atm.
Assume that the total volume of blood in the body is 5.0 L.
Calculate the mass and volume (at 37°C and atmospheric pressure (p(N2) = 0.80 atm) of N2 gas released as a diver surfaces.
*Think of the carbonation of a soda bottle (the diver) under pressure in a sealed can compared to a flat soda. Essentially you are calculating how much nitrogen a diver has to exhale as he surfaces in order to avoid getting the bends.
