Choose one answer.

a. 85
b. 102
c. 124
d. 158
e. 210

I keep using equation delta G=delta H-T(delta S).......I plug in numbers but keep getting 147.5K then if I am trying to get celcius I get 125 which only thing close is 124 and not sure if its right once I manipulate to get T.

    Check your algebra. I get something like 400 K (close to that) and that -273.15 = very close to 124. (123.8 or something like that).
