Question

Ethyl achohol has a heat of vaporization of 850. J/g. What mass of ethyl alcohol can be boiled using 15000 j of energy

Answer 1

I believe you would divide 15000 by 850 to get 1.76g of ethyl alcohol

Answer 2

You can boil 17.6g of ethyl alcohol with 15000J of energy.

Step-by-step explanation:

Heat of vaporization is defined as the amount of energy that must be added to a liquid substance to transform this substance into a gas.

The heat of vaporization of ethyl alcohol is 850 J/g. That means with 850 J you can boil 1g of ethyl alcohol. Now, 15000J can boil:

15000J × (1g / 850J) = 17.6g

Thus, you can boil 17.6g of ethyl alcohol with 15000J of energy.
