How many liters of gaseous hydrogen bromide at \( 35.0^{\circ} \mathrm{C} \) and 0.629 atm will a chemist need in order to prepare 3.50 L of 1.20 M hydrobromic acid? Round your answer to 3 significant figures. Note: Reference the Fundamental constants table for additional information.

\( 9.00 \times 10^{-3} \mathrm{~mol} \) of HBr are dissolved in water to make 19.0 L of solution. What is the concentration of hydroxide ions, \( \left[\mathrm{OH}^{-}\right] \), in this solution? Express your answer with the appropriate units. View Available Hint(s)

Concentrated \( \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2} \) is 17.0 M . Determine the volume in mL of the concentrated solution required to produce 2800 mL of \( 0.656 \mathrm{M} \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2} \)

If the \( \left[\mathrm{H}_{3} \mathrm{O}^{+}\right] \)is less than \( \left[\mathrm{OH}^{-}\right] \)in aqueous solution, then the solution is said to be
