Answer :
Answer: 40%
Step-by-step explanation:
The formula to calculate the percent error is given by :-
[tex]\text{percent error}=\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\\[/tex]
Given : Actual volume = 1.5 liters
Estimated volume = 2.1 liters
Then, the percent error is given by :_
[tex]\text{percent error}=\dfrac{|2.1-1.5|}{1.5}\times100\\\\\Rightarrow\ \text{percent error}=\dfrac{|0.6|}{1.5}\times100\\\\\Rightarrow\ \text{percent error}=\dfrac{0.6}{1.5}\times100\\\\\Rightarrow\ \text{percent error}=0.4\times100=40\%[/tex]
Hence, the percent error = 40%
