The empirical formula of a compound is $C{H}_{2}O$ . 0.0835 moles of the compound contains 1.0 g of hydrogen atoms. Molecular formula of the compound is _____?

Given, $EF=C{H}_{2}O$

Let the molecular formula be ${\left(C{H}_{2}O\right)}_n$

1 mole of a compound contains 2n moles of H atoms or n moles of Hydrogen$\left(H_2\right)$

0.0835 mole of the compound will contain 0.0835n moles of Hydrogen ($H_2$) 

= 0.1670n moles of H atom

$0.1670n=1$

$n=1÷0.1670=5.9\approx 6$

$\therefore$The molecular formula is $C_6{H}_{12}{O}_6$
