1. A gas occupying a volume of 725mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final the volume?

2. The volume of a gas is 5.80L, measured at 1.00 atm. What is the pressure of the as in mmHG if the volume is changed to 9.65 L? (The temperature remains constant).

3. Calculate the work done in when 50.0g of tin dissolves in excess acid at 1.00 atm and 25 degrees C:

Assume ideal gas behavior.

4. a 0.1375-g sample of solid magnesium is burned in a constant -volume bomb calorimeter that has a heat capacity of 3024 J/ degree C. The temperature increases by 1,126 degree C. Calculate the heat given off by the burning Mg, in kJ/g and in kJ/mol.
