# The amount of a chemical solution is measured to be 2 liters. What is the percent error of the measurement?

25%

#### Explanation:

2 liters may be $1.5 \text{to} 1.9$ rounded up to $2 \mathmr{and} 2.1 \mathmr{and} 2.4$ rounded down to 2.

$2 - 1.5 = 0.5$

percent error = $\left(\text{absolute error" /" quantity}\right) \cdot 100$

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