"0.538 g" would be the mass of the water.

Given values are:

Hydrated salt,

  • 1.167 g

Anhydrous salt,

  • 0.629 g

→ The mass of water lost by the salt will be:

= [tex]Hydrated \ salt - Anhydrous \ salt[/tex]

By substituting the given values, we get\

= [tex]1.167-0.629[/tex]

= [tex]0.538 \ g[/tex]

Thus the above answer is appropriate.
