Chapter 7, Problem 7.39E

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

a. $\text{26}\text{.5}\text{g}$ of solute is dissolved in $\text{200}\text{.}\text{mL}$ of water to give a solution with a density of $\text{1}\text{.10}\text{g}/\text{mL}$.

b. A $\text{30}\text{.0-mL}$ solution sample on evaporation leaves a solid residue of $\text{0}\text{.38}\text{g}$.

c. On analysis for total protein, a blood serum sample of $\text{15}\text{.0}\text{mL}$ is found to contain $\text{1}\text{.15}\text{g}$ of total protein.
