Asample of the hydrate of sodium carbonate has a mass of 8.85 g. it loses 1.28 g when heated. find the molar ratio of this compound and classify the type of hydrate.

Molar ratio of the compound is 1:1 and the type of hydrate is Mono hydrate.

Explanation:

From the given,

Mass of sodium carbonate = 8.85 g

Loss mass = 1.28 g

Actual weight of sodium carbonate = 8.85 g - 1.28 g = 7.57 g

Therefore, the compound has only one water molecule.

Molecular formula of the compound is an name of the compound is sodium carbonate mono hydrate.

Hence, the type of the compound is Mono hydrate.
