Question

9. If the experimental density of water is 1.15 g/ml and the stated density of water is 1.00 g/ml, what isthe percent error for the experimental density of water?

Answer 1

The percentage error is 13.04%

Step-by-step explanation

Given that;

Exact value = 1.15 g/ml

Approximate value = 1.00 g/ml

Follow the steps below to find the percentage error of water

Step 1; Apply the percentage error formula

`\begin{gathered} \text{ Percentage error = }\frac{\text{ approximate value - exact value }}{\text{ exact value}}*\text{ 100\%} \\ \\ \text{ Percentage error = }\frac{\text{ 1.00 - 1.15}}{\text{ 1.15}}*\text{ 100\%} \\ \\ \text{ Percentage error = }\frac{\text{ }\lvert{-0.15}\rvert}{\text{ 1.15}}*\text{ 100\%} \\ \\ \text{ Percentage error = 0.1304 }*\text{ 100\%} \\ \text{ Percentage error = 13.04 \%} \end{gathered}`

Therefore, the percentage error is 13.04%
