A balloon containing 134.4g of dioxygen is linked to a nanometer that indicates a pressure of 85.00 kPa. What will be the new pressure if we add 207.2g of dinitrogen, while doubling the absolute temperature and while decreasing the volume by 1/3 of its value?

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
