Chapter 3, Problem 89P(choose chapter or problem)
Hydrogen fluoride is used in the manufacture of Freons (which destroy ozone in the stratosphere) and in the production of aluminum metal. It is prepared by the reaction
\(\mathrm{CaF}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \longrightarrow \mathrm{CaSO}_{4}+2 \mathrm{HF}\)
In one process, 6.00 kg of \(\mathrm{CaF}_{2}\) are treated with an excess of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) and yield 2.86 kg of HF. Calculate the percent yield of HF.

ANSWER:
Step 1 of 2
Here we have to calculate the percent yield of HF.
Given:
The balanced chemical reaction is,
Mass of = 6.00 kg
Actual yield of HF = 2.86 kg
The % yield can be calculated as ,
% yield =
100 %
