Question

Determine the amount of energy required to boil 50 g of
ethanol.

Answer 1

42050 J.

Step-by-step explanation:

Data obtained from the question:

Mass (M) of ethanol = 50g

Heat of vaporisation (ΔHv) of ethanol = 841 J/g

Heat (Q) =.?

The heat required to boil 50g of ethanol can be obtained as follow:

Q = MΔHv

Q = 50 x 841

Q = 42050 J.

Therefore, the heat required to boil 50g of ethanol is 42050 J.
