Answer:
Calculation of Molar mass of a compound
We can find the molecular mass of the molecule by following the given substance:
Identify the formula of the compound or molecule
Using the formula determine the number of atoms present in each element of the compound or molecule
Multiply the atomic weight of each element with the number of atoms of that particular element
Similarly, do it for all the elements in the molecule or compound
Add up all the values obtained in the above step
Then add the unit as grams/mole you will get the molecular mass of the substance
Molar mass of water
One mole of H2O is made up of 2 moles of hydrogen atoms and 1 mole of oxygen atom.
Molar mass of atoms
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
