If carbon (C, with an atomic weight of 12, combines with oxygen (O), with an atomic weight of 16, to form carbon dioxide (CO2), how many grams of carbon would react with 176g of oxygen?

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.
