a) Determine the solubility of potassium nitrate at 50oC
b) determine the molar concentration of saturated potassium nitrate at 50o(K = 39.0; 0 = 16.0; N = 14.0 and density of water 1g/cm3)

  

Answers


John
a) Solubility = 79g per 100g water

b) R.F.M of KNO3 = 101

Molar concentration = $\frac{79}{101}$ x $\frac{1000}{100}$ = 7.8 M
