Complete combustion of \( X \) g of an organic compound gave \( 0.25 \) g of \( \mathrm{CO_2} \) and \( 0.12 \) g of \( \mathrm{H_2O} \). If the \( \% \) of carbon is \( 25\% \) and of hydrogen is \( 4.89\% \), then \( X = \) ______ \( \times 10^{-3} \) g. (Nearest integer)
(Molar mass of \( \mathrm{C} \), \( \mathrm{H} \) and \( \mathrm{O} \) are \( 12 \), \( 1 \) and \( 16 \) g \( \mathrm{mol}^{-1} \) respectively.)
