What is the gas pressure?

**drwls**, Tuesday, November 23, 2010 at 6:00amUse the initial set of numbers and the ideal gas law to compute the number of moles, n.

n = PV/(RT)= 2.5*3.5/(0.0826*350)= 0.304 moles

I used R = 0.0826 liter*atm/(mole K)

Then use the ideal gas law again with the above value of n to solve for the unknown P.

P = nRT/V
