Question

Calculate no of atoms in 0.2 mole molecule of Nitrogen

Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Number}\mathrm{of}\mathrm{atoms}=\mathrm{Number}\mathrm{of}\mathrm{moles}\times \mathrm{Avogadro}\mathrm{number} \\ \mathrm{Therefore},\mathrm{no}.\mathrm{of}\mathrm{atoms}=0.2\times 6.022\times {10}^{23}=1.204\times {10}^{23}\mathrm{atoms} \end{gathered}$$
