When 2016 J of heat energy is added to 49.5 g of ethanol, C2H6O, the temperature increases by 16.6 °C. Calculate the molar heat capacity of C2H6O.

49.5g = 2.98mols

C=q/n*temperature change in Celsius
2016/2.98*16.6

woah there, watch out

molar mass of 46.08 g/mol
2(12.01) + 6(1.01) + 16 = 46.08 g

thus,
49.5 g * (1 mol/46.08 g) ≈ 1.07 mol

oops, typo on my part second line should say:

molar mass of "ethanol should be" 46.08 g/mol
