Question

Calculate the molecular mass of water. (Atomic mass of Hydrogen is 1 u, Atomic mass of Oxygen is 16 u) write it on a sheet of a paper and explanation also

Answer 1

Answer:

Mass of 1 mole of Hydrogen atoms= 1 g /mol

Mass of 1mole of Oxygen atoms = 16 g/mol

Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.

Mass of one mole of Oxygen atoms = 1 x 16 g /mol

On adding all the above-obtained values we get,

Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

Answer

Molar mass of water = 18g/mol
