"We know that in any substance its mole number is the weight of the substance divided by the molar mass of that substance.

No. of moles = Weight in grams/Molar mass

Molar mass is calculated by using the atomic masses of the various elements present in the compound.

Molar mass = ∑[(No. of atoms of an element)*(Mass of atom of that element)]

Given, No. of moles of water = 5 moles

Water is represented as H2O.

Atomic mass of Hydrogen = 1 amu

Atomic mass of Oxygen = 16 amu

Molar mass of water = (2*1)+(1*16) = 18 g/mole

Thus, the weight in grams = No. of moles * molar mass = 5*18 = 90 grams"
