A 5.0g of salt was weighted by Tunde as 5.1g. What is the percentage error?
- 20
-
2
- 1.1
- 0.2
The correct answer is: B
Explanation
% error = \(\frac{\text{actual error}}{\text{true value}}\) x 100
Where actual error = 5.1 - 5.0 = 0.1
true value = 5.0g
% error = \(\frac{0.1}{5.0}\) x 100
= \(\frac{10}{5}\)
= 2%
