A 1,000 mL solution of acetic acid contains 26 mL of pure acetic acid. Find the percent concentration of this solution.

Mrac [35]

Given:

Total solution : 1000mL

Pure acetic acid = 26mL

To find:

The percent concentration of given solution.

Solution:

We know that,

$\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100$

Putting the given values, we get

$\text{Percent concentration}=\dfrac{26}{1000}\times 100$

$\text{Percent concentration}=\dfrac{26}{10}$

$\text{Percent concentration}=2.6$

Therefore, the percent concentration of this solution is 2.6%.

The data set 80, 84, 79, 44, 87, 73, 89, 90, 82, 89, 93, 97, 77, and 71 is graphed below. A graph shows the horizontal axis labe

Based on the information given, it can be deduced that the distribution is a skewed distribution and the best choice is a median.

<h3>How to calculate the mean.</h3>

The mean will be:

= (80 + 84 + 79 + 44 + 87 + 73 + 89 + 90 + 82 + 89 + 93 + 97 + 77 + 71) / 14

= 1135/14

= 81.07

The median will be the middle number after the numbers are arranged in ascending order. This will be:

44, 71, 73, 77, 79, 80, 82, 84, 87, 89, 89, 90, 93, and 97. Therefore, the median will be:

= (82 + 84) / 2

= 83

Lastly, the measure of center that is the best choice for this data set is median.
