help solve with steps and answer please

(R=0.0821L.atm/mol.K) 1. A 200mL sample of nitrogen gas is collected at 45.0C and a pressure of 610 torr. What volume will the gas occupy at 0C and 760 torr? 2. A 4.50-L gas sample is collected at temperature and pressure of 27C and 1.20atm. The gas is transferred to a 3.00-L container at a pressure of 1.00atm. What must the Celsius temperature of the gas in the 3.00-L container be? 3. What minimum pressure would a 250mL aerosol at 20C can have to withstand it were to contain 2.00L of gas measured at 700 torr and a temperature of 77C ? 4. Calculate the volume occupied by 25.50g of ammonia at a pressure of 2.75atm and a temperature of 55.0C. 5. Suppose 12.0g of dry ice (solid CO2 ) was placed in an empty 400mL steel cylinder. What pressure would develop if all the solid sublimed at temperature of 35.0C ? 6. Calculate the temperatures (in Celsius) of nitrogen gas sample that has a volume of 2.25L and a pressure of 300 torr and contains 0.500 mole of nitrogen 7. The heat of vaporization of water is 540cal/g. How many calories are required to vaporize 5.00kg of boiling water
