The weight of oxalic acid required to neutralize $100 \, cc$ of a normal solution of $NaOH$ is ........ $gm$.

The mass of $CO_2$ that will be obtained by heating $10 \ kg$ of $80 \%$ pure limestone $(CaCO_3)$ is ............... $kg$.

According to the reaction,$Mg_{(s)} + 2HCl_{(aq)} \longrightarrow MgCl_{2_{(aq)}} + H_{2_{(g)}} \uparrow$,calculate the mass of $Mg$ required to liberate $4.48 \ dm^3$ of $H_2$ gas at $STP$. (Molar mass of $Mg = 24 \ g \ mol^{-1}$) (in $g$)

The density (in $g \; mL^{-1}$) of a $3.60 \; M$ sulphuric acid solution that is $29 \%$ $H_2SO_4$ (molar mass $= 98 \; g \; mol^{-1}$) by mass will be

What is the volume occupied by $32 \ g$ methane gas at $STP$ (in $dm^3$)?

$15 \ mL$ of $N/10$ $NaOH$ solution completely neutralizes $12 \ mL$ of $H_2SO_4$ solution. The normality of $H_2SO_4$ solution will be:
