How would you prepare a 10% by mass aqueous solution of NH4Cl?

Answer:

1) Calculate the molarity of the NH3 solution that you have. Then you can use the formula V·C = V·C (volume and concentration), V (NH3) · C (NH3) = 500 mL · 0.2 M

2) Calculate the mass of NH4Cl necessary to end with 0.2 M in 500 mL.

3) Add the volume necessary of NH3 and the mass necessary of NH4Cl, and fill the rest with water.

Hope it helps...

But, are you sure you don't need look into the pH of the buffer?
