What volume will 0.780 moles of Xe occupy at STP?

Question

Quizplus · Accepted Answer

According to the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. At STP (standard temperature and pressure), the temperature is 273 K and the pressure is 1 atm. Therefore, we can rearrange the ideal gas law to solve for volume: V = nRT/P = (0.780 mol)(0.08206 L⋅atm/mol⋅K)(273 K)/(1 atm) = 17.5 L. So the correct choice is D) 17.5 L.
