Oxygen can be generated by the reaction of Hydrogen Peroxide with Manganese $($IV$)$ oxide.

$2H_2{O}_2(aq)+Mn{O}_2(s)2H_{2}O(l)+Mn(s)+2O_2(g)$

Imagine in lab, you used nine test tubes and placed different masses of $Mn{O}_2$ in each test tube. An equal amount of $H_2{O}_2$ was added to each test tube, and the volume of gas produced was measured each minute for five minutes. The data from the experiment is as follows:

Volume of $O_2($in $mL)$ measured at $1-$minute intervals for varying masses of $Mn{O}_2$
