A student reads the volume in a buret as 7.89 ml. The teacher checks the buret, and the actual value for the volume is 7.77 ml. What is the student's percent error?

Answer:

1.54%

Explanation:

Percent error is found as finding the value of measured value versus actual value, dividing it by the actual value written in absolute notation (percent error, the accuracy of the measured value cannot be negative) times 100 to find it as percent.

This is how we express it as a formula:

[tex]percent~error=\frac{|measured-actual|}{actual} * 100%[/tex]

Plugging in the numbers means we have to understand what goes where. Measured value is what the student measured, and the actual value is the correct answer.

Given this information,

[tex]percent~error=\frac{|7.89-7.77|}{7.77} * 100\\percent~error=\frac{|0.12|}{7.77} *100\\percent~error=0.015444*100\\percent~error=1.54%[/tex]
