Chapter 7, Problem 7.34E

Calculate the concentration in $\%\left(\text{v}/\text{v}\right)$ of the following solutions:

a. $200.\text{mL}$ of solution contains $15\text{mL}$ of alcohol.

b. $200.\text{mL}$ of solution contains $15\text{mL}$ of any soluble liquid solute.

c. $\text{8}\text{.0}\text{fluid}\text{ounces}$ of oil is added to $\text{2}\text{.0}\text{gallons}$ $\left(\text{256}\text{fluid}\text{ounces}\right)$ of gasoline.

d. A solution of alcohol and water is separated by distillation. A $\text{200}\text{.-mL}$ sample gives $85.9\text{mL}$ of alcohol.
