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.

the answer is 303.15 or 303

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
