Question

The accepted measurement of the volume of a liquid

sample is 15.20 mL. If the student's measurement is
14.80 mL. What is the percentage of error?
A-(4.25%
B-(1.75%)
C-(3.50%)
D-(2.63 %)

Answer 1

D-(2.63 %)

Step-by-step explanation:

Percentage Error

Is the difference between the approximate and the exact or accepted value of a measurement, as a percentage of the exact or accepted value.

The formula is:

`\displaystyle \delta=\left |(va-ve)/(ve) \right |\cdot 100\%`

The accepted value of the volume of a liquid sample is va=15.20 ml and the student's measurement is ve=14.80 ml. The percentage of error is:

`\displaystyle \delta=\left |(15.20-14.80)/(15.20)\right |\cdot 100\%`

`\displaystyle \delta=\left |(0.4)/(15.20)\right |\cdot 100\%`

`\delta=2.63\%`

Correct choice: D-(2.63 %)
