Question:

Manganese dioxide reacts with hydrochloric acid as shown in the chemical equation.

{eq}MnO_2(s)+4HCl(aq) \rightarrow MnCl_2O(l)+Cl_2(g) {/eq}

What is the percent yield of the reaction if 5.75 g of {eq}H_2O {/eq} is obtained when 28 g of {eq}MnO_2 {/eq} and 28g of {eq}HCl {/eq} are mixed and allowed to react?

Percent Yield:

Always desired the calculated yield along with actual yield for determining the percent yield. For the estimation of percent yield, one can utilize the formula as shown below.

{eq}{\rm{\% }}\;{\rm{yield}} = \dfrac{{{\rm{Actual}}\;{\rm{mass}}}}{{{\rm{Calculated}}\;{\rm{mass}}}} \times 100\% {/eq}
