Question

What is w when a gas is compressed from 49.7 L to 37.7 L using a constant external pressure of 747 Torr?

Note: 760 Torr = 1 atm = 1.01325 bar = 101.325 kPa
work = -p(v2 - v1)
is pressure 747/760?
That answer I gave you will be in units of Liter*atm. You can change that to J by multiplying by 101.325.
101.325 x L*atm = J
Yes. P is 747/760 = ? atm.
so, -(.98)(37.7-49.7)?
I would use another place in the 0.98 since there are three places in the other numbers.
