Not sure what I am doing wrong... 1. The problem statement, all variables and given/known data A chemical reaction takes place in a container of cross-sectional area 100 cm2. As a result of the reaction, a piston is pushed out through 20 cm against an external pressure of 567 torr. What is the value for w for this reaction? (Sign does matter.) Answer in units of J. 2. Relevant equations w = - (Pressure)(Change in Volume) 3. The attempt at a solution Cross sectional area = 100 cm^2 = .01 m^2 Change is piston distance = 20cm = .2 m Pressure = 567 torr x 133.322 = 75593.574 Pa Solution disregarding sign = [75593.574 kg/(m*s^2)][.01 m^2][.2 m] ---> 151.188 J However this is coming up as incorrect.
