Calculate the molality of 1 litre solution of 90
WebSome chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter). To calculate the molarity of a 70 wt. % nitric acid the number of moles of HNO 3 present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413 WebMay 2, 2024 · The molarity and molality of the solution are 17.5 M and 135.5 m respectively. Explanation: 93% by mass of sulfuric acid means that 93 grams of sulfuric acid is present in 100 grams of solution. Mass of solvent = 100 - 93 = 7g. To calculate the volume of solution, we use the equation: To calculate the molarity of solution, we use … WebMass of H 2 SO 4 in 100ml of 93% H 2 SO 4 solution = 93g. ∴ Mass of H 2 SO 4 in 1000 ml of the H 2 SO 4 solution = 930g. Mass of 1000 ml H 2 SO 4 solution = 1000 × 1.84 = … buffalo wild wings dickson city
