Explanation:
The given data is as follows.
= 225.5 mL,
= 45.00 mL
= 0.09988 M,
= ?
Therefore, formula to calculate final concentration will be as follows.
=
Putting the given values into the above formula as follows.
=
=
= 0.5 M
Thus, we can conclude that the final concentration of the given solution is 0.5 M.
% composition of ethanol = 34.51%
% composition of water = 65.49%
<h3>What is density?</h3>A material's density is defined as its mass per unit volume.
Given data:
The density of ethanol = 0.7890 g/mL
The density of water = 0.9982 g/mL
The density of mixture = 0.926 g/mL
Let the % composition of ethanol = x
Let the % composition of water = 100-x
Now density of the mixture
%
Hence,
% composition of ethanol = 34.51%
% composition of water = 65.49%
