Question

N (H2O) = 31 моль Найти m​

Answer 1

Ответ:

Объяснение:

Дано

n(H2O) = 31 моль

М(Н2О) = 18 г/моль

Найти

m(H2O)

m(H2O) = n * M = 31 * 18 =558 г

Answer 2

To find the molar mass (m) of a compound, we need to know the chemical formula of the compound. In this case, you mentioned "N (H2O) = 31 mol," but it seems incomplete or unclear.

If you can provide the complete chemical formula, I'll be able to assist you in finding the molar mass.
