Answer : The amount of water lost was, 333.4 grams.

Explanation : Given,

Heat released = 753480 J

Formula used :

$Q=mL$

where,

Q = heat released = 753480 J

m = mass = ?

L = latent heat vaporization of water = $2260J/g$

Now put all the given values in the above formula, we get:

$753480J=m\times (2260J/g)$

$m=333.4g$

Thus, the amount of water lost was, 333.4 grams.
