Question

For the following reaction, 6.00 grams of calcium hydroxide are mixed with excess hydrochloric acid. The reaction yields 7.64 grams of calcium chloride.

calcium hydroxide (aq) + hydrochloric acid (aq) calcium chloride (aq) + water (1)

What is the theoretical yield of calcium chloride? 9 grams

What is the percent yield of calcium chloride? 84.8 %​

Answer 1

8.986 g and 85%

Step-by-step explanation:

Theoretical Yield:

`6.00 \: g \: Ca(OH₂) * (1 \: mol \: Ca(OH₂))/(74.10g \: Ca(OH₂)) * (1 \: mol \: CaCl₂)/(1 \: mol \: Ca(OH₂)) * (111.0 \: g \: CaCl₂)/(1 \: mol \:CaCl₂ ) = 8.986 \: g \: CaCl₂`

Percent Yield:

`(7.64 \: g)/(8.986 \: g) * 100 = 85.0\%`
