    An organic compound contains 14 atoms of carbon per molecules. If mass % of carbon in the compound is 22.4% , then molecular mass of the compound will be:

    The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a carbon-12 atom taken as 12 units. The molecular mass of a substance indicates the number of times one molecule of a substance is heavier than (1)/(12) th of C-12 atom. It is equal to the sum of atomic masses of all the atoms present in a molecule. Depending on the number of atoms of same or different elements present in the molecule, it can be monoatomic, diatomic, triatomic, tetraatomic or a poly-atomic molecule. Which is an example of a poly-atomic molecule?
