Question 1 - 24 January - Shift 1
Uracil is base present in RNA with the following structure. $\%$ of $N$ in uracil is _____.
Given :
Molar mass $N=14$ $ g$ $ mol^{-1} ; O=16 $ $g $ $mol^{-1} ; C=$ $12 $ $g$ $ mol^{-1} ; H=1$ $ g $ $mol^{-1}$;
Show Answer
Answer: (25)
Solution:
Formula: Nucleotide Base
Mol. Wt of $C_4 N_2 H_4 O_2=112$
$\% N=\frac{28}{112} \times 100=25 \%$
