0.73%

Explanation:

We are given that the accepted mass of an object is 150 grams while Paul determines it to be 148.9 grams and we are to find the percent error.

We know the formula for the percent error:  

Percentage error = (| experimental value - actual value | / actual value) * 100

So substituting the given values in the above formula:  

Percent error = (| 148.9 - 150| / 150) * 100 = 0.0730*100 = 0.73%
