Answer the question below?

Question

A student performs a lab producing a product that she is able to dry and mass. If she gets a mass of product of 12.38 g in lab, but theoretically she should have produced 21.89 g.

what is the percent error?

Answer 1

Hi there! To solve for percent error, you are going to use the following equation:

[(theoretical mass - experimental mass)/theoretical mass]*100%

For example, if your theoretical mass was 10g and the mass obtained experimentally was 8g, you would have:

[(10g-8g)/10g]*100%

(2g/10g)*100%

(0.2)*100%

20% error

Hope this helps!
