Q9P Ammonia reacts with hypobromite,... [FREE SOLUTION]

Chapter 7: Q9P (page 158)

Ammonia reacts with hypobromite, ${OBr}^{-}, {OBr}^{-}$ by the reaction ${2NH}_{3} + 30 {Br}^{-} 鈫� N_{2} + 3 {Br}^{-} + 3 H_{2} O$ . What is the molarity of a hypobromite solution $1.00 mL$ of the ${OBr}^{-}$ solution reacts with $1.69 mg of {NH}_{3}$

Short Answer

Expert verified

The molarity of ${OBr}^{-}$ is $M_{OBr} = 0.15 {MOBr}^{-}$

Step by step solution

Define the molarity.

The total number of moles of solute per litre of solution is known as a solution's molarity. Because, unlike mass, the volume of a system fluctuates with changes in physical conditions, the molality of a solution is affected by changes in physical parameters of the system such as pressure and temperature. Molarity is represented by the letter M, which stands for molar.

The molarity of a solution is defined as one gramme of solute dissolved in one liter of solution.

Calculate the molarity of OBr

$Volume of {OBr}^{-} = 1.00 mL = 0.001 L mass of {NH}_{3} = 1.69 mg = 0.00169 g FM of {NH}_{3} = 117.03 g / mol Now use mole concept and molarity formula to calculate the molarity of {OBr}^{-}, M_{{OBr}^{-} = \frac{0.00169 {gNH}_{3} (\frac{1 {molNH}_{3}}{17.03 {gNH}_{3}}) (\frac{3 {molOBr}^{-}}{2 {molNH}_{3}})}{0.001 L}} = 0.15 \frac{mol OBr}{L} = 0.15 {MOBr}^{-} Thus, the molarity of OBr is M_{OBr} = 0.15 {MOBr}^{-}$
