Introduction to Chemistry
Which of the following equations is derived from the ideal gas law to calculate the number of moles when pressure, volume, and temperature are known?
A gas is contained in a cylinder with a movable piston. Initially, the gas has a pressure of 2 atm and a volume of 4 L. If the pressure changes to 4 atm while the temperature remains constant, what is the new volume of the gas?
A gas occupies a volume of 5 L at 2 atm pressure and 300 K. What is the number of moles of the gas?
