Question

a reaction takes place that is expected to yield 171.9g of product but only yields 154.8 what is the percent error for this experiment​

Answer 1

Given info : A reaction takes place that is expected to yield 171.9 g of products but only yield 154.8 g.

To find : The percentage error for this experiment is ..

solution : theoretical value = expected to yield amount of product = 171.9 g

practical value = yield in actual amount = 154.8 g

percentage error for this experiment = (theoretical value - practical value)/theoretical value × 100

= (171.9 - 154.8)/171.9 × 100

= 17.1/171.9 × 100

= 1710/171.9

= 9.947 %

Therefore the percentage error for this experiment is 9.947 %
