Hello guys! I am having a bit of trouble with the question my chemistry teacher has given me.

The question sounds as follows:
Calculate how to make 20 ml of a solution of NH₄Cl with pH = 5.0

Thank you before hand.

Calculate how to make 20 ml of a solution of NH₄Cl with pH = 5.0
1. Write the equation of reaction of NH4Cl (or simply - NH4+) with the water.
2. Calculate the reaction constant.
3. Calculate concentration of NH4Cl at pH = 5,0.
4. Calculate the mass of NH4Cl for 20 ml solution.
