Calculate the concentration interms of mass by volume percentage of the solution containing. 2.5g potassium chloride in 50ml of potassium chloride (KCl)solution? Ans: (5%) |
|
Answer» Given CONDITIONS ⇒ Mass of the Potassium Chloride = 2.5 g. Volume of the Potassium Chloride SOLUTION = 50 mL. ∵ Concentration = Mass/Volume ∴ Concentration of the Potassium Chloride in Solution = 2.5/50 = 0.05 g/mL. ∴ Mass-volume Concentration in % = 0.05 × 100 = 5 % Hope it helps. |
