Question

What is the percent water in the compound barium chloride dihydrate?

Answer 1

Answer : 14.751

Explanation:

Barium chloride dihydrate is an ionic compound that contains water molecules in its crystal structure I.e hydrate. The water that's part of the solid crystal structure is called water of crystallisation.

Barium chloride dihydrate has a molar mass of 244. 26 gmol-1 , which means that one mole of dihydrate 244.26g .

since one mole of hydrate contains 2moles of water , and since water has a molar mass of 18.015g mol-1 , it follows that u get 2× 18.015gmol-1 of water for every 244.26 g of hydrate.

percent composition of water is

2×18.015 /244.26 × 100= 14.751.
