Convert 2097 psi to atm.
2097 psi/14.7 = ? atm
Convert 1000 g to mol Ar. mol = grams/molar mass.
Use PV = nRT, substitute and solve for V = volume.
Then reuse PV = nRT, substitute the new P, the old V, R, and new T and solve for n. Then n = grams/molar mass, you know n and molar mass, solve for grams.
Don't forget T must be in kelvin.
