Calculate the main-sequence lifetime of the Sun by first determining the rate at which it burns hydrogen (refer to chapter 12 ) and then dividing that rate into its core mass. If your answer is in seconds, convert to years, given that there are about $3.2 \times 10^{7}$ seconds in a year.

In the text, it was stated that the reaction $4^{1} \mathrm{H} \rightarrow_{2}^{4} \mathrm{He}+2_{1}^{0} \mathrm{e}+2 v_{\mathrm{e}}+_{0}^{0} \gamma$ is the mechanism by which hydrogen in stars is converted into helium and that the reaction releases about $26.7 \mathrm{MeV}$ of energy. The sun radiates energy at the rate of $3.9 \times 10^{26} \mathrm{W}$ and has a mass of about $1.99 \times 10^{30} \mathrm{kg}$, of which $75 \%$ is hydrogen. Find out how long it will take the sun to convert $12 \%$ of its hydrogen into helium.
