$7.5 \ g$ of a gas occupies $5.8 \ L$ of volume at $STP$. The gas is

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 $KClO_{3(s)} = 122.5 \ g/mol$)

What is the volume in $litres$ of the gas produced at $NTP$ by the reaction of $100 \ g$ of $CaC_2$ with water?
$CaC_2 + 2H_2O \rightarrow Ca(OH)_2 + C_2H_2$

How many $ml$ of $1 \, (M) \, H_2SO_4$ are required to neutralize $10 \, ml$ of $1 \, (M) \, NaOH$ solution?

The molarity of a $98\%$ by weight solution of $H_2SO_4$ is .......... $M$. The density of the solution at $35^o C$ is $1.84 \ g/cm^3$.

At $T \ K$,$3 \ moles$ of hydrogen and $1 \ mole$ of $N_2$ are allowed to react to form ammonia. When $1 \ mole$ of ammonia is formed,the total pressure in the vessel is $15 \ atm$. The partial pressure of $N_2$ in the vessel (in $atm$) is (in $.5$)
