Uracil is a base present in RNA with the following structure. \( \% \) of \( \mathrm{N} \) in uracil is \( \_\_\_\_\_ \).
Given:
Molar mass \( \mathrm{N} = 14 \, \mathrm{g\,mol^{-1}} \)
\( \mathrm{O} = 16 \, \mathrm{g\,mol^{-1}} \)
\( \mathrm{C} = 12 \, \mathrm{g\,mol^{-1}} \)
\( \mathrm{H} = 1 \, \mathrm{g\,mol^{-1}} \)
