Step 1

Given:

Mass of hydrate before heating (Mn(ClO4)2.nH2O) = 2.126 g

Mass of hydrate after heating Mn(ClO4)2 = 1.473 g.

Chemical reaction is given by:

Mn(ClO4)2. nH20 - Mn(Cl04)2 nH20

Step 2

Calculation for mass of water:

Mass of water = Mass of hydrate before heating (Mn(ClO4)2.nH2O - Mass of hydrate after heating Mn(ClO4)2

Mass of water = 2.126 g – 1.473 g = 0.653 g.
