Remember what your units are: J/(K mol).
81.6 J are required to raise the temperature of one mole of methanol by one degree. Therefore if you have ...
Remembering our units J/K mol we determine how many moles are in 20g of methanol. How much heat required can be determined by: specific heat x # degrees x # moles. Full solution. 125 words.
