Learning chemistry

FROM CHEMISTRY HERE IS AN IMPORTANT TERM THAT CAN HELP YOU A LOT...


The terms are as follows:-

MOLECULAR MASS:- Molecular mass is the sum of atomic masses of the elements present in a molecule.
It is obtained by multiplying the atomic mass of each element to the number of its atoms and adding them together.

for example:- Molecular mass of -
glucose(C6H12O6) :-
carbon's atomic mass = 12u
hydrogen's atomic mass= 1u
oxygen's atomic mass= 16u
so molecular mass of glucose = (6 X 12)+(12 X 1)+(6 X 16)
= 72 + 12 + 96
= 180u
