What is the volume of 1.40 moles of chlorine gas at STP?

Question

Quizplus · Accepted Answer

According to the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. At STP (standard temperature and pressure), the pressure is 1 atm and the temperature is 273 K. Therefore, we can rearrange the equation as V = (nRT)/P and substitute the values to get V = (1.40 mol x 0.0821 L·atm/mol·K x 273 K)/1 atm = 31.4 L. Therefore, choice A is the best answer.
