Question

1. In chemical calculations if the atomic mass of carbon was fix 120 amu, the value of the avogadro constant would be

Answer 1

avogadro no = no of atoms in 12 g of carbon 12 isotope

according to question

6.022* 10^23 = 12g/120

6.022*10^24 is the avogadro constant when carbon is 120 amu
