\mathrm{\text { Moles of } A \text { remain after } 30 \text { days }=\frac{N_0}{2^n}=\frac{1}{2^3}=\frac{1}{8}}

\mathrm{\left\{n=\frac{30}{10}=3\right\}}

\mathrm{\text { Moles of A converted to product }=1-\frac{1}{8}=\frac{7}{8} \mathrm{mol}}

\mathrm{\text { 5o, moles of } C=\frac{k_2}{k_1+k_2+k_3} \times \frac{7}{8} \times \frac{5}{1}=1.46 mol}
