1. A container holds three different gases. The partial pressures are: 25 kPa, 42 kPa, and 63 kPa. Find the total pressure. 2. A balloon contains mostly helium and a little methane. The partial pressure of helium is 101.2 kPa. If the pressure inside the balloon is 101.30 kPa, what is the partial pressure of methane? 3. A tank holds two gases. The total pressure is 150. atm. If the partial pressure of one of the gases is 35 atm. Find the pressure of the other gas. 4. A tank is filled with oxygen and nitrogen. The total pressure of the tank is 6.45 atm, and the partial pressure of the nitrogen is 2.07 atm. What is the partial pressure of the oxygen?

Question
Only need help on the first 3, if you feel generous you can do 4 but if not no problem :)
1. A container holds three different gases. The partial pressures are: 25 kPa, 42 kPa, and 63 kPa. Find the total
pressure.
2. A balloon contains mostly helium and a little methane. The partial pressure of helium is 101.2 kPa. If the
pressure
inside the balloon is 101.30 kPa, what is the partial pressure of methane?
3. A tank holds two gases. The total pressure is 150. atm. If the partial pressure of one of the gases is 35 atm.
Find the pressure of the other gas.
4. A tank is filled with oxygen and nitrogen. The total pressure of the tank is 6.45 atm, and the partial pressure
of the nitrogen is 2.07 atm. What is the partial pressure of the oxygen?
