Answer:
34.21%
Explanation:
Given parameters:
Mass of ethylene glycol in the container = 130g
Mass of the liquid in total = 380g
Unkown:
Percentage of ethylene glycol in the liquid =?
Solution
To find the percentage of the ethylene glycol in liquid, we use the expression below:
Percentage of ethylene glycol in liquid =
x 100
Percentage of ethylene glycol =
x 100
Percentage of ethylene glycol = 34.21%
<u>Answer:</u>
<u>For a):</u> The mass percent of naphthalene in the original sample is 31.00 %.
<u>For b):</u> The mass percent of 3-nitroaniline in the original sample is 32.03 %.
<u>For c):</u> The mass percent of benzoic acid in the original sample is 29.97 %.
<u>For d):</u> The total percent recovered is 93.00 %.
<u>Explanation:</u>
Percentage by mass is defined as the ratio of the mass of a substance to the mass of the solution multiplied by 100. The formula used for this is:
......(1)
a):
Mass of naphthalene = 0.483 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

b):
Mass of 3-nitroaniline = 0.499 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

c):
Mass of benzoic acid = 0.467 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

d):
Total mass recovered = [0.483 + 0.499 + 0.467] = 1.449 g
Mass of the sample = 1.558 g
Plugging values in equation 1:
