If I have 17 moles of gas at a temperature of 67 °C, and a volume of 88.89 liters, what is the pressure of the gas?

Answer 1

Assuming ideal gas behavior...

PV = nRT

P = pressure = ?

V = volume in liters = 88.89 L

n = moles = 17

R = gas constant = 0.0821 Latm/Kmol

T = temperature in Kelvin = 67C +273 = 340K

Solve for P:

P = nRT / V

Plug in the values and solve. Units will be in atmospheres of pressure.
