What is the percent error when a student measures the volume to be 19.3 liters when
katrin2010 [14]

Answer:

The answer is

<h2>13.84 %</h2>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual volume = 22.4 L

error = 22.4 - 19.3 = 3.1

The percentage error is

P(\%) =  \frac{3.1}{22.4}  \times 100 \\  = 13.839285714...

We have the final answer as

<h3>13.84 %</h3>

Hope this helps you

Consider two solutions, solution a and solution
Ronch [10]
Answer is: solution A has 2,57 time greater pH value than solution B.<span>
</span>Concentration of [H⁺] in solution A is than 370x.
pH = -log[H⁺].
pH(solution A) = -log(370x).
pH(solution b) = -log(x).
pH(solution A) / pH(solution B) = -log(370x) / -log(x).
pH(solution A) / pH(solution B) = 2,57.
