Answer to Question #319983 in General Chemistry for Ivan Ackerman

Question

A sample of 89.1 g of tetraphosphorous decoxide (P4⁢O10) reacts with 49.0 g of water to produce phosphoric acid (H3⁢PO4) according to the following balanced equation.

P4O10+6H2O⟶4H3PO4

Determine the limiting reactant for the reaction.

Calculate the mass of H3⁢PO4 produced in the reaction.

Calculate the percent yield of H3⁢PO4 is isolated after carrying out the reaction.

Answer 1

The limiting reactant is P₄O₁₀

Mass of H₃PO₄ is 122.98 g

To find out the percent yield of H3PO4 you need to know the theoretical yield.
