A scuba diver's tank contains 0.29 kg of O₂ compressed into 2.3 L.
a) Calculate the gas pressure inside the tank at 9 degrees Celsius.
b) What volume would this oxygen occupy at 26 degrees Celsius and 0.95 atm?
Please show your work and explain your reasoning.

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
