Q30. A star has $100 \%$ helium composition. It starts to convert three ${ } ^ { 4 } \mathrm { He }$ into one ${ } ^ { 12 } \mathrm { C }$ via triple alpha process as ${ } ^ { 4 } \mathrm { He } + { } ^ { 4 } \mathrm { He } + { } ^ { 4 } \mathrm { He } \rightarrow { } ^ { 12 } \mathrm { C } + \mathrm { Q }$. The mass of the star is $2.0 \times 10 ^ { 32 } \mathrm {~kg}$ and it generates energy at the rate of $5.808 \times 10 ^ { 30 } \mathrm {~W}$. The rate of converting these ${ } ^ { 4 } \mathrm { He }$ to ${ } ^ { 12 } \mathrm { C }$ is $\mathrm { n } \times 10 ^ { 42 } \mathrm {~s} ^ { - 1 }$, where n is $\_\_\_\_$ [ Take, mass of ${ } ^ { 4 } \mathrm { He } = 4.0026 \mathrm { u }$, mass of ${ } ^ { 12 } \mathrm { C } = 12 \mathrm { u }$ ]
