How many moles of molecular oxygen are required to produce a pressure of 0.413 bar in a 650 mL container with a temperature of 245 K?

Question

Quizplus · Accepted Answer

The ideal gas law can be used to calculate the number of moles of molecular oxygen required to produce a pressure of 0.413 bar in a 650 mL container with a temperature of 245 K. The ideal gas law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. Solving for n, we get n = PV/RT. Plugging in the given values, we get n = (0.413 bar)(0.650 L)/(0.0821 L*atm/(mol*K))(245 K) = 0.0132 mol.
