Thus the volume of the solution comes out to be 2.68x 10 -2 litres. Putting in the original formula, m= n/v =4.27×10 -2 moles / 2.68x 10 -2 litres. The answer is 1.59 M. Example 2: If a solution contains 15 grams of sodium sulphate and the volume comes out to be 125 millilitres.

Molarity Formula Molarity Definition and Formula
WebCalculate the mole fraction of each gas in the mixture. Solution The given parameters are NHe = 4.5 x 103 mol and NO2 = 1.0 x 103 mol Mole fraction can be calculated as XHe = 4.5 x 103 mol / (4.5 x 103 mol + 1.0 x 103 mol) XHe = 4.5 mol / 5.5 mol XHe = 0.82 XO2 = (2.0 x 103 mol / (4.5 x 103 mol + 1.0 x 103 mol) XO2 = 1.0 x 103 / 5.5 x 103 WebMolarity = Moles of Solute / Volume of Solution in Litre Molar mass of Co (NO 3) 2 .6H 2 O (solute) = 59 + 2 (14 + 3 × 16) + 6 × 18 = 291 g.mol -1 ∴ Moles of Co (NO 3) 2 .6H 2 O = 30 / 291 mol = 0.103 mol Therefore, molarity = 0.103 mol / 4.3 L = 0.023 M Number of moles present in 1000 mL (Solvent) of 0.5 M H 2 SO 4 (Solute) = 0.5 mol WebFormula of molarity Molarity= Moles of solute Volume of solution in litre Example of molarity 1. 25 mol L - 1 or 1. 25 M solution of KOH means that 1. 25 mol of KOH has been dissolved in one liter (or one cubic decimetre). Molality Molality (m) is defined as the number of moles of the solute per kilogram (kg) of the solvent. Formula for molality infowindow vue
