Please tell me if these are right?
A mixture of oxygen and helium is prepared for a scuba diver that will descend to 125 feet below the ocean surface. At that depth the diver breathes a gas mixture that has a total pressure of 8atm. If the particle pressure of the oxygen in the tank at that depth is 1010 mmHg, what is the particle pressure of the helium?
I got 6.67 atm, 7atm in S.F.
Calculate the pressure, in atmospheres of 2.00 moles of helium gas in a 10.0 Liter container at 27 digress C.
I got 4.93 atm.
