Find the weight in grams of carbon monoxide $(CO)$ that contains the same number of oxygen atoms as are present in $22 \ g$ of carbon dioxide $(CO_2)$.

When $1 \ L$ of $CO_2$ is heated with graphite,the volume of the gases collected is $1.8 \ L$. What will be the number of moles of $CO$ produced at $STP$?

At $STP$,'$x$' $g$ of a metal hydrogen carbonate $(MHCO_3)$ (molar mass $84 \ g \ mol^{-1}$) on heating gives $CO_2$,which can completely react with $0.2 \ mol$ of $MOH$ (molar mass $40 \ g \ mol^{-1}$) to give $MHCO_3$. The value of '$x$' is

Chemical equations convey quantitative information on the

$0.01$ mole of iodoform $(CHI_3)$ reacts with $Ag$ to produce a gas whose volume at $NTP$ is ............. $mL$.
$2CHI_3 + 6Ag \to 6AgI_{(s)} + C_2H_{2(g)}$

What is the mass of $KClO_{3(s)}$ required to liberate $22.4 \ dm^3$ of oxygen at $STP$ during thermal decomposition (in $g$)? (Molar Mass of $KClO_{3(s)} = 122.5 \ g/mol$)
