Question

Determine the of a solution that is 0.2 m NH₃ and 0.35m NH₄Cl .

Answer 1

To determine the molarity of a solution containing 0.2 M NH₃ and 0.35 M NH₄Cl, calculate the total moles of solute in the solution and divide by the total volume of the solution.

Step-by-step explanation:

To determine the molarity of a solution containing 0.2 M NH₃ and 0.35 M NH₄Cl, we need to calculate the total moles of solute in the solution and then divide it by the total volume of the solution.

1. Calculate the moles of NH₃:
   moles of NH₃ = Molarity x Volume
   moles of NH₃ = 0.2 M x 1 L = 0.2 moles
2. Calculate the moles of NH₄Cl:
   moles of NH₄Cl = Molarity x Volume
   moles of NH₄Cl = 0.35 M x 1 L = 0.35 moles
3. Calculate the total moles of solute:
   total moles = moles of NH₃ + moles of NH₄Cl
   total moles = 0.2 moles + 0.35 moles = 0.55 moles
4. Calculate the molarity of the solution:
   Molarity = total moles / total volume
   Molarity = 0.55 moles / 1 L = 0.55 M

Therefore, the molarity of the solution containing 0.2 M NH₃ and 0.35 M NH₄Cl is 0.55 M.
