Answer:
the concentration of the mixture is 41%
Explanation:
To find the concentration of the mixture, we need to calculate the average of the concentrations of the two acid solutions.
The first acid solution has a concentration of 46% and a volume of 3 fl. oz.
The second acid solution has a concentration of 38% and a volume of 5 fl. oz.
To find the concentration of the mixture, we can use the following formula:
Concentration of mixture = (concentration of solution 1 × volume of solution 1 + concentration of solution 2 × volume of solution 2) / total volume
Plugging in the values:
Concentration of mixture = (46% × 3 fl. oz. + 38% × 5 fl. oz.) / (3 fl. oz. + 5 fl. oz.)
Calculating the numerator:
(46% × 3 fl. oz. + 38% × 5 fl. oz.) = (1.38 + 1.9) = 3.28
Calculating the denominator:
(3 fl. oz. + 5 fl. oz.) = 8 fl. oz.
Calculating the final concentration:
Concentration of mixture = 3.28 / 8 = 0.41 or 41%
Therefore, the concentration of the mixture is 41%.
