A gas evoked during the fermentation of glucose has a volume of 0.781 L at STP. What was the volume of this gas at the fermentation temperature of 36.5oC and 1.20 atm pressure?

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.
