WebAlternate preparation of 0.01 N Sulfuric acid: Preparation: Transfer 10 ml of 1 N sulfuric acid volumetric solution to a 1000 ml of volumetric flask and dilute to volume with water. Standardization: Weigh accurately about 0.05g of Tromethamine dried and dissolve to 50ml with water. Perform Potentiometric Titration due to lower concentration. 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. dgft itc hs
