Chapter 4, Problem 76E

The phosphorus pentoxide used to produce phosphoric acid for cola soft drinks is prepared by burning phosphorus in oxygen.

(a) What is the limiting reactant when 0.200 mol of P₄ and 0.200 mol of 02 react according to

${\text{P}}_4+5{\text{O}}_2\to {\text{P}}_4{\text{O}}_{10}$

(b) Calculate the percent yield if 10.0 g of ${\text{P}}_4{\text{O}}_{10}$ is isolated from the reaction.
