a) calculate the gas pressure inside the tank at 9 celsius
b)what volume would this oxygen occupy at 26 celsius and 0.95 atm
plz show work and how
1 Answer

Moles O2 = 290 g / 32 g/mol =9.06
T = 273 + 9 = 282 K
p = nRT/ V = 9.06 x 0.0821 x 282 / 2.3 = 91.2 atm
T = 26 + 273 =299 K
V = nRT /p = 9.06 x 0.0821 x 299 / 0.95 = 234 L
