Question$(0.37)\left(\frac{1.29}{m}\right)=0.444 \mathrm{~g} / \mathrm{mL} \mathrm{HCl} \quad \frac{36.465 \mathrm{~mol}}{30}$ A solution contains 50.0 grams of glycerol, $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}$, and 50.0 grams of water. The solution has a density of $1.10 \mathrm{~g} / \mathrm{mL}$. Calculate the following: a) Weight $\%$ of $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}$ in this solution. $\frac{50}{1000}=50 \%$ b) Molality of $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}$ in this solution. $\mathrm{M}=\frac{n \text { sowt }}{\text { soleat } \mathrm{ky}}=\frac{0.54 \mathrm{mI1}}{0.05}=10.8 \mathrm{M}$ c) Mole Fraction of $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}$ in this solution. $x=\frac{0.54}{2 . \pi}$ d) Molarity of $\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{3}$ in this solution. $$m=\frac{n}{c}=0.54$$
