Give the concentration of each type of ion in the following solutions: a. 0.50 M Co(NO 3) 2 b. 1 M Fe(ClO 4) 3 3. Calculate the number of moles of Cl-ions in 1.75 L of 1.0 x 10-3 M ZnCl 2. WebCalculate the molality of 1 litre solution containing 93 % H 2SO 4 (W/V) if the density of the solution is 1.84 g mL −1. Medium Solution Verified by Toppr 93 % H 2SO 4 w/v means 93 g of H 2SO 4 is present in 100cc of solution. Since volume is 1000ml, amount of H 2SO 4 is 930 g/litre. Also density is given 1.84g/ml

WebJun 14, 2012 · What is the molality of the solution? The molar mass of KCl is 74.5513 g. So first I got g of KCl solute: .273 (m) * 74.5513 (g/m) = 20.35 g Total mass of solution = 1020.35g (since 1000g solvent per .273m solute). Now density = mass/volume Thus, volume = mass/density: V = 1020.35 (g) / 1.011 (g/ml) = 1009 mL or 1.009 L Now, molarity = … WebA 10.00-mL sample of a 24.00% solution of ammonium bromide (NH4Br) requires 23.41 mL of 1.200 molar silver nitrate (AgNO3) to react with all of the bromide ion present.
