WebSolution. Part- 1: Given data. Density ρ ρ ( ρ) = 1. 8 gml - 1. 98 % w / w solution ⇒ 98 g solute is present in 100 g solution. Part- 2 Calculating molarity ( M) Molarity ( M) of a solution is defined as the number of moles per litre of solution. The solution contains 98 g H 2 SO 4, so the number of moles = 98 98 = 1 m o l. Web15 de set. de 2024 · Normality (N) = weight of solute / Volume of the solution in liters × Equivalent weight of solute N = (4/40) × (1000/310) = 0.1 × 3.2258 = 0.3225 N Example 2: When 19.0 ml of the citric acid solution is titrated with 30.09 mL of 0.1811 N KOH, what is the citric acid concentration?

WebCorrect option is B) For acids, Normality = molarity × basicity. So, Normality = 0.3×2=0.6. ∵ Basicity of H 3PO 3 is 2 because one of the H is not replaceable in H3PO3. The H atoms which are linked to oxygen are replaceable, but H atom linked directly to central atom P is nonreplaceable. Hence, the correct option is B. Web10 de mar. de 2015 · 3. Molarity (M) is defined as moles of solute per liter of solution while Normality (N) is defined as moles of reacting units per liter of solution.
