Question
When a solution of hydrogen bromide is prepared, $1.283 \mathrm{~L}$ of HBr gas at $25^{\circ} \mathrm{C}$ and 0.974 atm is bubbled into $250.0 \mathrm{~mL}$ of water. Assuming all the HBr dissolves with no volume change, what is the molarity of the hydrobromic acid solution produced?
Step 1
Here, $P$ is the pressure, $V$ is the volume, $n$ is the number of moles, $R$ is the gas constant, and $T$ is the temperature. We want to find the number of moles, so we rearrange the equation to solve for $n$: \[n = \frac{PV}{RT}\] Show more…

Calculate the molarity of a solution of hydrobromic acid (HBr) if 30.35 $\mathrm{mL}$ of 0.1000 $\mathrm{M} \mathrm{NaOH}$ is required to titrate 25.00 $\mathrm{mL}$ of the acid to the equivalence point.
What is the molarity of concentrated HBr solution if the acid is 48.0% by mass HBr? D = 1.50 g/mL. What volume of concentrated HNO3 should be used to prepare 1.0 liter of 0.15M HNO3? Concentrated HNO3 is 70.0% by mass HNO3 with a density of 1.42 g/mL.
Calculate the molarity of a solution of hydrobromic acid $(\mathrm{HBr})$ if 30.35 $\mathrm{mL}$ of 0.1000 $\mathrm{M}$ NaOH is required to titrate 25.00 $\mathrm{mL}$ of the acid to the equivalence point.
