Problem: A sample of 4.0 moles of helium gas is confined to a 24.0 Liter balloon at 176 °C at 6.0 atm. The balloon expands while temperature remains constant to 36.0 Liters. What is the new pressure?A) 2.0 atmB) 3.0 atmC) 4.0 atmD) 8.0 atmE) 9.0 atm

FREE Expert Solution

We are asked to calculate the new pressure when a 24.0 L at 6.0 atm expands to 36.0 L at a constant temperature. 

Recall that the ideal gas law is:


PV=nRT


The pressure and volume of a gas are related to the number of moles, gas constant and temperatureThe value nRT is constant
