45.2 grams of aluminum nitrate are reacted with 71.9 mL of a 0.880 M solution of calcium sulfide. The balanced chemical equation can be seen below:
LaTeX: 2Al\left(NO_3\right)_3\:+\:3\:CaS\:\longrightarrow\:Al_2S_3\:+\:3Ca\left(NO_3\right)_22 A l ( N O 3 ) 3 + 3 C a S ⟶ A l 2 S 3 + 3 C a ( N O 3 ) 2
If 2.95 grams of precipitate is filtered out of the resulting solution, what is the actual yield?

Explanation:
The mass of a substance can be calculated from it's mole value by using the formula:
mole = mass/molar mass
According to this question, there are 0.250 moles of copper. Hence, the mass of copper can be calculated as follows:
Molar mass of Cu = 63.55g/mol
0.250 = mass/63.55
mass = 0.250 × 63.55
mass = 15.8875
Mass of Cu in 0.250mol is 15.89grams.
