Answer 2

Answer:
`(1)/(\Delta H_(fusion))* 1kJ* xg/mol`

Step-by-step explanation:

Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure.

If
`\Delta H_(fusion)` is used to melt = 1 mole of solid

1 kJ of energy is used to melt =
`(1)/(\Delta H_(fusion))* 1kJ`

Now if molar mass of solid is x g/mol

Then mass of solid will be =
`(1)/(\Delta H_(fusion))* 1kJ* xg/mol`
