A.Three gases (18.0 g of ethane, 8.00 g of methane, CH4, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. The total pressure in the container is 3.70 atm at 23.0 oC. Determine the partial pressure of each gas in the container.
State the pressure values numerically in atmospheres, which is separated by the commas. Enter the partial pressure of methane first, then ethane, then propane.
B. A gaseous mixture of O2 and N2 which is having the 40.8 % nitrogen by mass. Calculate the partial pressure of oxygen in the mixture if the total pressure is 525 mmHg?
