How many moles of an ideal gas are required to produce a pressure of 3.00 bar in a 1.50 L container with a temperature of 25.0 °C?

Question

Quizplus · Accepted Answer

We can first use the ideal gas law, PV = nRT, to solve for the number of moles of gas present:
n = PV/RT
n = (3.00 bar)(1.50 L)/(0.0831 L bar/mol K)(298 K)
n = 0.1818 mol
Rounding to three significant figures gives 0.182 mol. Therefore, the best choice is C.
