How do i calculated ∆G for ATP hydrolysis...?
if [ATP]= 2x10^-3 M, [ADP]= 10^-4 M and [Pi]=10^-2 M
the ∆G^o’ for the hydrolysis of ATP is -37.9jK/mol

Use the equation ∆G = ∆G^o + RTlnQ
Using the equation for ATP hydrolysis and the concentrations given you can work out Q.
ATP --> ADP + Pi
Q = [ADP][Pi] / [ATP]
Q = (10^-4 x 10^-2) / 2x10^-3
Q = 0.0005
Then substitute this value into the equation ∆G = ∆G^o + RTlnQ, along with R (8.314 J/mol K), T (assuming a temperature of 25C, which is equal to 298K) and the value of ∆G^o that you were given (converted to J/mol).
∆G = -37900J/mol + (8.314J/mol K x 298K x ln0.0005)
∆G = -37900J/mol + -18832J/mol
∆G = -56732J/mol
∆G = -56.7kJ/mol
