What is the volume occupied by 7.0 g of hydrogen under a pressure of 2.6 atm and a temperature of 300 K?

answer is .0332 m^3. how?

A steel cylinder of radius 7.0 cm and length 4.0 cm is placed in end-to-end thermal contact with a copper cylinder of the same dimensions. If the free ends of the two cylinders are maintained at constant temperatures of 85°C (steel) and 20°C (copper), how much heat will flow through the cylinders in 19 min?

answer is 1.17*10^6. how?

THANKS A TON. test on these tomorrow and ive been trying to do em for like an hour :\
