Solution Preparation

Q$9.$ Write a step$-$by$-$step procedure to prepare $500mL$ of $0\mathrm{.}150NaN{O}_3$ solution. Sodium nitrate $(NaN{O}_3)$ is a solid at room temperature.

Q$10.$ Write a step$-$by$-$step procedure to prepare $200m{L}_{0\mathrm{.}20}HN{O}_3$ from $16\mathrm{.}0MHN{O}_{3(aq)}($concentrated nitric acid$).$ Show work and pay attention to significant figures.

In your procedure, be clear concerning the following. $($a$)$ Concentrated acids are very corrosive. $($b$)$ Upon addition of water, concentrated acids may generate heat and boil or splash over. It is more prudent to add acid to water, than to add water to the acid.
