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
Molar mass:
Molar mass of any element is equal to the atomic mass of that element in the unit of grams. Molar mass is also equal to the mass of 6.02*10^23 atoms of that element.
The water or H2O is formed from 2 mole of hydrogen and one one of oxygen
The molar mass of H = 1.008 g/ mole
The molar mass of O= 16.00g/ mole
Therefore the molar mass of water = 2* 1.008 g/ mole+16.00g/ mole
=18.02 / mole
