A balloon containing helium gas contains 0.32 mol He at 2432 mmHg and 25 degreesC. The volume of the helium is 2.45L. If an additional 0.14 mol of He is injected into the balloon while the temperature and pressure constant, what is the volume of the helium.
Poisonous carbon monoxide gas is a product of the internal combustion engine. If 1.2 mol of Co at 11degreesC and 102mmHg are present in a container, what will be the volume of the CO gas?
