If the temperature of 34.4 g of ethanol increases from 25 to 78.8, how much has been absorbed by the ethanol?

Question

The specific heat of ethanol is 2.44.

Answer 1

q = mCdeltaT

q = (34.4 g)(2.44 J/g/deg)(78.8-25) = 83,936 J (83.9 kJ)

(this calculation assumes the units for specific heat are J/g-deg)
