so here i am doing my hw worksheet on the ideal gas law/ghram's law ad i have gotten to this one problem where i am totally stuck and confused. Please help me by telling me how to set this up and giving me tips, if necessary.
What is the mass(in grams) of ammonia gas(NH{tiny #3at the bottom},17g/mole contained in a 4.00 flask at 32.5 degrees Celsius and 1.6atm?

chemistry 
DrBob222,
PV = nRT
P = 1.6 atm
V = 4.00 L or whatever unit you didn't type in.
R = 0.08206 Latm.
T = 273 + 32.5 = ??K
n = solve for this.
Then n = grams/molar mass
You know n from above, grams is what you want and molar mass NH3 = 17 g/mole.
