A 250.0 gram block is placed on a balance. The balance measures the mass of the block as 243.9 grams. What is the percent error of the block

To compute the percent error, you divide the absolute difference between the actual value and the measured value with the actual value. Then, multiply it with 100 to get the percentage. The solution is as follows:

Percent error = (250 - 243.9) / 250 * 100

Percent error = 2.44%
