A 5.0g of salt was weighted by Tunde as 5.1g. What is the percentage error?
-
A.
20 -
B.
2 -
C.
1.1 -
D.
0.2
Correct Answer: Option 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%
