Nuclear Fission & Fusion question from JEE Main 2024 (9 Apr, Shift 1)

A star has $100\%$ helium composition. It starts to convert three ${}^{4}\text{He}$ into one ${}^{12}\text{C}$ via triple alpha process as ${}^{4}\text{He} + {}^{4}\text{He} + {}^{4}\text{He} \rightarrow {}^{12}\text{C} + \text{Q}$. The mass of the star is $2.0 \times 10^{32}\text{ kg}$ and it generates energy at the rate of $5.808 \times 10^{30}\text{ W}$. The rate of converting these ${}^{4}\text{He}$ to ${}^{12}\text{C}$ is $\text{n} \times 10^{42}\text{ s}^{-1}$, where $\text{n}$ is _________. [ Take, mass of ${}^{4}\text{He} = 4.0026\text{u}$, mass of ${}^{12}\text{C} = 12\text{u}$]
