Answer to Question #101613 in General Chemistry for Gloria

Question

For the following reaction, 5.80 grams of sulfuric acid are mixed with excess calcium hydroxide. The reaction yields 5.77 grams of calcium sulfate.

Answer 1

H2SO4+Ca(OH)2$\to$ CaSO4+2H2O

n(H2SO4)=5.8(g)/98.078(g/mol)=0.059(mol)

m(CaSO4)=136.14(g/mol)*0.059(mol)=8.032(g)

experimental yield =5.77(g)/8.032(g)*100%=71.84%
