(Sig figs will need to be accounted for - you nay beed a better number than 2.V = 10.the gas contant, on l-atm/deg-mole is 0.Solve for P - which will be a number on the order of 200 atm.You need to plug in more accurate values and report this to at least three significant figures.......
What pressure would 500 grams of hydrogen gas by kept at if you had a volume of 10.50 liters at 100 K?

-
H2 has a mass of 2 g/mole - so you have 250 moles. (Sig figs will need to be accounted for - you nay beed a better number than 2.)

P = nRT/V

n = 250
T = 100 K
V = 10.50
the gas contant, on l-atm/deg-mole is 0.082

Solve for P - which will be a number on the order of 200 atm. You need to plug in more accurate values and report this to at least three significant figures.
