Question

The heat of vaporization for ethanol is 0.826 kJ/j. Calculate the heat energy in joules required to boil 45.65g of ethanol

Answer 1

Step-by-step explanation:

Supposing the temperature of the ethanol is already at the ethanol's boiling point:

(0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J

Answer 2

ethanol is already at the ethanol's boiling point: (0.826 kJ/g) x (70.05 g) = 57.8613 kJ = 5.79 x 10^4 J.
