Question

If the atomics mass of oxygen were taken as 100 then molar mass of watee would be

Answer 1

Answer:Molar mass of a molecule or compound is defined as the sum of atomic mass of all the atoms present in the given formula.

For example, molar mass of H2O = atomic mass of hydrogen + atomic mass of oxygen

                   = 2×(1.00)g/mol + 16g/mol

                   = 18 g/mol

Now, when the atomic mass of oxygen is 100 g/mol then molar mass of water will be as follows.

        Molar mass of H2O =atomic mass of hydrogen + atomic mass of oxygen

                   = 2×(1.00)g/mol + 100g/mol

                   = 102 g/mol

Thus, we can conclude that if the atomic mass of oxygen were taken as 100,then molar mass of water would be 102 g/mol.
