Question

A student measures the mass of a sample as 9.67g. Calculate the percent error , given that the correct mass is 9.87. Show step-by-step calculation.

Answer 1

In order to calculate this, you need to solve :

$\frac{9.87 - 9.67}{9.87}$   x 100 %

= 0.2 / 9.87    x 100 %

= 2.02 %

Hope this helps

Answer 2

9.87-9.67/9.81*100 percent

   

= 0.2 / 9.87  *100 percent

= 0.020
