Question

austin calculated that he should be able to make 6.7064 g of alum based on his mass of aluminum. after the experiment, austin weighed his alum on the balance and recorded a mass of 5.3335 g. what was his percent yield?

Explanation:

Step1: Recall the formula for percent yield

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

Step2: Identify the actual and theoretical yields

Theoretical yield = $6.7064$ g, actual yield = $5.3335$ g

Step3: Substitute values into the formula

Percent yield = $\frac{5.3335}{6.7064}\times100\%$
Calculate $\frac{5.3335}{6.7064}\approx0.7953$
Then $0.7953\times100\% = 79.53\%$

Answer:

$79.53\%$
