Calculate the number of moles of gas contained in a 10.0 L tank at 22°C and 105 atm.(R = 0.08206 L.atm/K*mol) A)1.71 × 10^-3 mol B)0.0231 mol C)1.03 mol D)43.4 mol E)582 mol

Question

Quizplus · Accepted Answer

We can use the ideal gas law to solve for the number of moles:
PV = nRT
n = PV/RT
n = (105 atm)(10.0 L)/(0.08206 L atm/mol K)(295 K) = 43.4 mol (rounded to two significant figures)
