The molecular formula of the chloride of a metal $M$ is $MCl_3$. The formula of its carbonate would be:

$0.24 \ g$ of an organic compound gave $0.22 \ g$ $CO_2$ on complete combustion. If it contains $1.66 \%$ hydrogen,then the percentage of $C$ and $O$ will be

If we want to study the relative arrangement of atoms in a molecule,we study:

$A$ compound contains $69.5\%$ oxygen and $30.5\%$ nitrogen and its molecular weight is $92$. The molecular formula of the compound is

An organic compound contains $C = 74.0\%$,$H = 8.65\%$ and $N = 17.3\%$. Its empirical formula is:

An organic compound on analysis gave $C = 48 \,g$, $H = 8 \,g$ and $N = 56 \,g$. The volume of $1.0 \,g$ of the compound was found to be $200 \,mL$ at $NTP$. What is the molecular formula of the compound?
