Chemistry - Mole Concept Question with Solution | TestHub

The phosphorus pentaoxide used to produce phosphoric acid for cola soft drinks is prepared by burning phosphorus in oxygen. Initially 0.2 mole of each ${\mathrm{P}}_4$ and ${\mathrm{O}}_2$ are taken. The % yield, if 10 gm of ${\mathrm{P}}_4{\mathrm{O}}_{10}$ is isolated from the reaction ${\mathrm{P}}_4+5{\mathrm{O}}_2\to {\mathrm{P}}_4{\mathrm{O}}_{10}$, is-
