Question

The amount of a chemical solution is measured to be 2 liters.

What is the percent error of the measurement?
A. 2.5%
B. 5%
C. 25%
D. 50%

Answer 1

the answer to this question is C.

Answer 2

2 liters may be 1.5 to 1.9 rounded up to 2 or 2.1 or 2.4 rounded down to 2.

2 - 1.5 = 0.5

percent error = (absolute error / quantity) * 100

percent error = 0.5/2 * 100% = 0.25 * 100% = 25%

Choice C. 25%.
