The molar mass of C2H6 is 30 {(12*2)+(1*6)}.

The number of moles(n)=mass/molar mass

n=9.3 g/ 30 g mol-1 =0.31 mol.

The number of molecules of C2H6 =n* Avogadro number(L)= 0.31*6.022*1023= 1.86682*1023

The no. of atoms in one mole of C2H6=8

The no. of atoms in 0.31 moles of C2H6=8*1.86682*1023 =14.93456*1023 =1.49*1024
