Question

fill in the missing words
note to students: for molar mass values, use periodic table from the textbook. all answers must be reported with the correct number of significant figures.
the theoretical yield of a chemical reaction is 3.5 grams of the product. the actual yield is 2.3 grams. the percent yield of the reaction is %.

Explanation:

Step1: Recall percent - yield formula

Percent yield = $\frac{\text{actual yield}}{\text{theoretical yield}}\times100\%$

Step2: Substitute given values

Percent yield = $\frac{2.3}{3.5}\times100\%$
Percent yield = $0.65714\times100\%$
Percent yield = $65.714\%$
Rounding to two significant figures, we get $66\%$

Answer:

$66$
