Concept explainers
Interpretation : The total mixture of the solution of benzene and ethanol is to be calculated.
Concept Introduction :
The density of the substance is the mass per unit volume. It is given as,
Where,

Answer to Problem 68A
The total mass of the mixture is
Explanation of Solution
Given information :
Volume of the ethanol,
Volume of the benzene,
Density of the ethanol,
Density of the benzene,
And,
Calculation: The density formula is represented as follows:
Firstly, calculate the mass of the ethanol by substituting the given values, such that,
Similarly, calculate the mass of the benzene,
ow, the total mass of the mixture is,
Now, substitute the values in this above equation, then
The mass of the solution after mixing the ethanol into benzene is
