Calculate each of the following quantities for an ideal gas?

Please help me to calculate the following quantities for an ideal gas?

  • a) The pressure decreased from 4 atm to 1520 mm Hg, while the temperature is decreased from 250°C to 212°F. b) The pressure is increased from 450 torr to 2280 mm Hg, while the temperature is increased from 212°F to 150°C.

  • Answer:

    Are you searching for the volume of gas present in each of these situations? PV=nRT will be your most useful tool P= Pressure V= Volume n= moles in your case one R= .08206 T = temperature in Kelvin For all the parts of this you can use deltaT or deltaP to find the deltaV. So just convert your values all to atm, degrees Kelvin, and then solve for V in liters and you will have your amount of V at the end of each. You can also solve for initial Volume and final volume using the same idea.
