Chapter 14 Problem 37. How did they get 94884.6/-30 from ((298.15x328.15))/((298.15-328.15))? When I enter it in my calculator I get -3261.26 where as 94884.6/-30 = -3162.82. When doing the math individually, the denominator I get -30 like theirs but the numerator I get 97837.92 which is different from their answer.Chemistry and Chemical Reactivity, 9th Edition
