Question

To make saturated solution 72g on NaCl Is dissolved in 200g of water at 293k. Calculate its Concentration at this temperature

Answer 1

ANSWER

26.47%

EXPLANATION

Mass of sodium chloride (Solute) = 36gm

Mass of sodium chloride (Solute) = 36gmMass of water (solvent) = 100 gm

Mass of sodium chloride (Solute) = 36gmMass of water (solvent) = 100 gmMass of solution = 36+100 = 136 gm

Mass of sodium chloride (Solute) = 36gmMass of water (solvent) = 100 gmMass of solution = 36+100 = 136 gmConcentration = (Mass of Solute / Mass of Solution) * 100

Mass of sodium chloride (Solute) = 36gmMass of water (solvent) = 100 gmMass of solution = 36+100 = 136 gmConcentration = (Mass of Solute / Mass of Solution) * 100Concentration = (36/136)*100 = 26.47%
