?The specific heat of octane, \(\mathrm{C}_{8} \mathrm{H}_{18}(l)\), is 2.22 J/g-K. (a)

Chapter 5, Problem 5.53

(choose chapter or problem)

The specific heat of octane, \(\mathrm{C}_{8} \mathrm{H}_{18}(l)\), is 2.22 J/g-K.

(a) How many J of heat are needed to raise the temperature of 80.0 g of octane from 10.0 to \(25.0^{\circ} \mathrm{C}\)?

(b) Which will require more heat, increasing the temperature of 1 mol of \(\mathrm{C}_{8} \mathrm{H}_{18}(l)\) by a certain amount or increasing the temperature of 1 mol of \(\mathrm{H}_{2} \mathrm{O}(l)\) by the same amount?
