8.9

Postby Gabriela Carrillo 1B » Sun Jan 21, 2018 4:26 pm

When calculating w, I understand how to calculate -1.48 L atm but how do we convert that to Joules to use in the equation to calculate the change in internal energy?

Use the equivalency of the ideal gas constants, 8.314 J K /mol = .08206 L atm / K mol . the - 1.48 is in L atm so through dimensional analysis of multiplying by 8.314 J K /mol over .08206 L atm / K mol , this should result in - 150 Joules.

To convert L/atm to Joules, you would multiply the L/atm amount by 101.325 joules, since 1 L/atm = 101.325 joules.
