Expert Answer:

Mass percentage can be found by using formulae.

Mass space percentage equals fraction numerator Mass space of space Solute over denominator Mass space of space Solution end fraction cross times 100
space space space

Molar mass can be found by adding atomic masses of all the elements present in that molecule .

For example,  H2O  =atomic mass of 2H  +  atomic mass of O  = 2+16 =18.

Hence the molar or molecular mass of Water is 18.
