Let ( m ) assume mo. of Oxygen Atoms be ( x ). then no of thydriogen atoms be ( 15 x ) Now ( perp g=0.00318 mathrm{mol} ) [ begin{array}{l} Rightarrow quad perp operatorname{mot}_{0}=frac{1}{0.00318} g Rightarrow 1 text { mole }=314.465 end{array} ] So, mole cular formule ( =C_{21} mathrm{H}_{30} mathrm{O}_{2} ) Option ( -B )
