Question

If 1 atom of an element weight 1.8*10^-22 gram. What is its atomic mass

Answer 1

let the atomic mass be x gram

x gram of elements contains avogadro no. of atoms = 6*10^23 atoms

weight of one atom = x/(6*10^23)

=1.8*10^-22

x = 6*10^23*1.8*10^-22

= 108 gram

hence the atomic mass is 108 gram
