Calculate the masses of (i) KNO3 and, separately, (ii) Ba(NO3)2 to add to a 0.110 mol kg^(-1) solution of KNO3(aq) containing 500 g of solvent to raise its ionic strength to 1.00.
Added by Julia C.
Step 1
First, we need to find the initial moles of KNO3 in the solution. We are given the molality (0.110 mol/kg) and the mass of the solvent (500 g). We can use the formula: Molality = moles of solute / mass of solvent (in kg) 0.110 mol/kg = moles of KNO3 / (500 g * Show more…

Calculate the theoretical mass of Potassium Nitrate (KNO3) required to prepare 100 mL solution with a concentration of 50 ppm N??
Madhur L.
A potassium nitrate solution is made by mixing 8.52 g of potassium nitrate with 120.0 mL of water. I calculated the number of moles of KNO3 0.08427 mol Determine the mass (in kg) of solvent used to make the solution. Assume that the density of water is 1.000 g/mL. Molar mass of KNO3 = 101.10 g/mol
