How many moles of

\mathrm{P}_4 \mathrm{O}_6

and

\mathrm{P}_4 \mathrm{O}_{10}

will be produced by the combustion of

12.4 \mathrm{~g}

of phosphorous (atomic mass 31) in

12.8 \mathrm{~g}

of oxygen, leaving no

\mathrm{P}_4

\mathrm{O}_2

View answer and explanation

Correct option: C

0.05 \mathrm{~mol}

each

Option C (

0.05 \mathrm{~mol}

each) is correct because the reaction stoichiometry and limiting reactant determine the moles of

\mathrm{P}_4 \mathrm{O}_6

and

\mathrm{P}_4 \mathrm{O}_{10}

produced.
