Solid potassium metal will react with chlorine gas to form potassium chloride. How many liters of chlorine gas are needed to completely react with .15g of potassium at 5 atm and 273k?

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.
