Question #9b45c

Answer 1

`1g`

Explanation:

For sake of ease let us follow CGS units.

We now that `1 J = 0.239005736 Cal`

`:.2.260xx10^3J~~540Cal`

We have water at `100^@C` and above calculated heat is supplied to it.
We also know that Latent heat of evaporation of water is `540cal//g`

Therefore we see that amount of water will evaporate `=1g`
