Practice Questions

Question 1

Question 2

A 8.50\,g sample of N$_2$ gas is contained in a 4.00\,L vessel at 300\,K. What is the pressure (in kPa) of the gas?

Question 3

If 3.00\,g of CH$_4$ is completely combusted at 298\,K and 150\,kPa, what volume of CO$_2$ (in liters) is produced? (M(CH$_4$)=16.04\,g/mol)

Question 4

A gas is collected over water at 25\,°C. The total pressure is 750\,mmHg and the vapor pressure of water is 23.8\,mmHg. What is the partial pressure of the dry gas?

Question 5

In the reaction C$_3$H$_8$+5O$_2$→3CO$_2$+4H$_2$O, if 2.00\,L of C$_3$H$_8$ and 8.00\,L of O$_2$ at the same temperature and pressure are mixed, which is the limiting reagent and what volume of CO$_2$ is produced?
