1.) A weather balloon is partially filled with helium to allow for expansion at high altitudes. At STP, a weather balloon is filled with enough helium to give a volume of 25.0 L. At an altitude of 30.0 km and -35 degrees Celsius, it has expanded to 2460 L. The increase in volume causes it to burst and a small parachute returns the instruments to earth.

a. How many grams of helium are added to the balloon?

b. What is the final pressure, in millimeters of mercury, of the helium inside the balloon when it burst?

2.) A mixture of nitrogen (N2) and helium has a volume of 250 mL at 30 degrees Celsius and a total pressure of 745 mmHg.

a. If the partial pressure of helium is 32 mmHg, what is the partial pressure of nitrogen?

b. What is the final volume , of the nitrogen at STP?

3.) A gas mixture contains oxygen and argon at partial pressures of 0.60atm and 425 mmHG. If nitrogen gas is added to the sample increases the total pressure to 1250 Torr, what is the partial pressure, in torr, of the nitrogen added?
