Asked by Lynden
A 1.07g sample of sulfur was burned in a bomb calorimeter whose calorimeter constant is 2.03 k cal/C. If the resulting temperature change was 1.17 C, what is the molar heat of combustion for sulfur?

S + O2 ==> SO2
q = Ccal x delta T
q = 2.03 kcal/c x 1.17 = ?
That q is for 1.07.
To find per grams it is
q/1.07 = ? kcal/g
And q/1.07 x molar mass S gives kcal/mol.
