Calculating Percent Yield

CHEM-FHWK1Z

Consider the following reaction:

$${Al}_{2}{O}_{3} + 3{H}_{2}O \rightarrow 2Al{(OH)}_{3}$$

50.0 g ${Al}_{2}{O}_{3}$ react with 30.0 g ${H}_{2}O$.

If 70.1 g $Al(O{H})_{3}$ are produced, what is the percent yield?

A periodic table is provided below.

A

91.6

B

80.9

C

87.6

D

89.9
