An organic compound contains 40% by weight of carbon and 6.66% by weight of Hydrogen. Empirical formula of the compound is

Moderate

Solution

$\mathrm{C}$ | $\mathrm{H}$ | $\mathrm{O}$ | |

$\mathrm{Percentage}\mathrm{of}\mathrm{weight}$ | $40$ | $6.66$ | $(100\u201346.66)=53.34$ |

$\mathrm{Number}\mathrm{of}\mathrm{gram}\mathrm{atoms}$ | $\frac{40}{12}=3.33$ | $\frac{6.66}{1}=6.66$ | $\frac{53.34}{16}=3.33$ |

$\mathrm{Number}\mathrm{of}\mathrm{gram}\mathrm{atoms}$ | $\frac{3.33}{3.33}=1$ | $\frac{6.66}{3.33}=2$ | $\frac{3.33}{3.33}=1$ |

$\mathrm{Empirical}\mathrm{Formula}$ = ${\mathrm{CH}}_{2}\mathrm{O}$
