The heat of vaporization is  =924.71  j/g

<em><u>explanation</u></em>

<u><em> </em></u>Heat of  vaporization is amount  of heat require   to vaporize  1  gram  of a substance.

Heat of  vaporization required is therefore=8720  joules/9.43  grams=924.71   j/g

How is stoichiometry used to calculate energy released when a mass of liquid freezes?
kati45 [8]

Answer:

D. Grams liquid x mol/g x delta Hf​reezing

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to reason that the stoichiometry used to calculate energy released when a mass of liquid freezes, involves the grams of the liquid, the molar mass of the liquid, as given in all the group choices, and the enthalpy of freezing because that is the process whereby a liquid goes solid.

In such a way, we infer that the correct factor would be D. Grams liquid x mol/g x delta Hf​reezing which sometimes is the negative of the enthalpy of fusion as they are contrary processes.

Regards!
