Avogadro no. = 6.02 × 10^{23}

Therefore, time taken

= \( \dfrac{6.02 \; \times \; 10^{23}}{10^{10}} s\)

= 6.02 × 10^{13 }s

= \( \dfrac{6.02 \; \times \; 10^{23}}{60 \; \times \; 60 \; \times \; 24 \; \times \; 365 } years\)

= 1.909 × 10^{6} years

Therefore, the time taken would be 1.909 × 10^{6} years.
