Can molecular mass be fractional
Solution:
Fractional atomic mass is the weighted average of all the naturally occurring isotopes of that element.
e.g., fractional atomic mass of chlorine is 35.5.
So, molecular mass of a compound can also be in fraction, when an element which have fractional atomic mass is present in that compound,
e.g., molecular mass of NaCl = 23+35.5 = 58.5
