PROBLEM 8.3.9. Calculate the mole fraction of each solute and solvent: 583 g of H 2 SO 4 in 1.50 kg of water—the acid solution used in an automobile battery. 0.86 g of NaCl in 1.00 × 10 2 g of water—a solution of sodium chloride for intravenous injection.
14 sty 2019 · Ways for Expressing Concentration of Solutions. – In this subject, we describe the four fundamental ways of expressing solution concentration: (1) molar concentration. (2) percent concentration. (3) solution-diluent volume ratio. (4) p-functions. (1) Molar Concentration.
13 lis 2022 · Calculate the concentration of a solution prepared by mixing given volumes to two solutions whose concentrations are expressed in the same units. Solutions are homogeneous (single-phase) mixtures of two or more components .
Problem #1: If you dilute 175 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution. Solution: M 1 V 1 = M 2 V 2 (1.6 mol/L) (175 mL) = (x) (1000 mL) x = 0.28 M. Note that 1000 mL was used rather than 1.0 L. Remember to keep the volume units consistent.
Problem #1: A solution of H 2 SO 4 with a molal concentration of 8.010 m has a density of 1.354 g/mL. What is the molar concentration of this solution? Solution: 8.010 m means 8.010 mol / 1 kg of solvent. (8.010 mol) (98.0768 g/mol) = 785.6 g of solute. 785.6 g + 1000 g = 1785.6 g total for solute and solvent in the 8.010 m solution.
This quiz helps you practice calculating the molarity (concentration) of a chemical solution with a variety of options, including dilutions.
