Which is the molar mass of H2O? 10.02 g/mol 16.00 g/mol 17.01 g/mol 18.02 g/mol
Elena-2011 [213]

Answer;

Molar mass of water is 18.02 g/mol

Explanation;

-Molar mass of a compound is determined by adding the relative atomic mass of each atom present in the compound. Molar mass of one mole of a compound, it is the weight in grams of  6.02 × 1023 atoms or molecules.

-Therefore; to calculate the molar mass of Water (H2O);  we first know the RAM of hydrogen and oxygen which are; H=1.01 and O= 16.00

Since there is two atom of hydrogen and one atom of oxygen in water;

Then; the Molar mass of water  will be; 2×1.01 + 1 ×16 = 18.02 g/mol
