Answer:
The water of crystallization for the formula of the unknown hydrate is 2.
Explanation:
Mass of an unknown hydrate = 1.000 g
Molar mass of hydrate = 195.5 g/mol
MOles of unknown hydrate =
Mass of hydrate after heating = 0.781 g
Mass of water lost due to heating = x
Moles of water lost =
1 Mole of hydrate has x moles of water and 0.00512 moles of hydrate has 0.0122 moles of water then we can write:
The water of crystallization for the formula of the unknown hydrate is 2.
