1) What mass of hydrogen gas will be produced rom 4.76g of NO and 3.23 g of CH4?

2NO(g)+2CH4(g)-->2HCN(g)+2H2O(g)+H2(g)

2) A 250.0g sample of a metal with a specific heat 0.95 J/g-C is heated to 80.0 C and then placed in a calorimeter with water. The initial temperature of the water is 19.0C and the final temperature of the system is 25.1 C. The heat loss to the calorimeter is negligible. What is the mass of the water?

3) Determine the volume and density of 45.0 g of ethane, C2H6, at STP.

4) A sample of sulfur dioxide occupies 12.0L at 258C and 1.27 psi. What volume will it occupy at STP?
