**DrBob222**, Tuesday, November 15, 2011 at 2:16pmUse PV = nRT and solve for n = number of moles.

Then n = grams/molar mass and solve for grams. You know the molar mass N2 = about 28

**25**, Tuesday, March 27, 2012 at 7:06pmPV=nRT

n=PV/RT

n=0.860*2.55/0.08206*(22.0+273.15)

n=2.19/24.2

n=0.0906 mole

0.0906molN*28.00g N/1 mole N

N=2.54g of N2
