Question

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

Answer 1

`25%`

Explanation:

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%`
