A rigid 224 L cylinder contains 240 grams of O2 and 70 grams

A rigid, 22.4 L cylinder contains 24.0 grams of O₂ and 7.0 grams of N₂. What is the total pressure in the cylinder at 0 ºC?

Solution

The total pressure is the total pressure of the cylinder. By dalton\'s law of partial pressures, the total pressure of the cylinder would be the pressure of the O2 gas and the N2 gas in the cylinder.

22.4 L cylinder contains 24.0 grams of O₂ and 7.0 grams of N₂.

moles of O2 =24 /32=0.75

moles of N2= 7/28 =0.25

total moles = 1 moles

PV= NRT

P= 1*0.0821*273 / 22.4 =1.0005 atm
