Question

make a saturated solution 36 gram of sodium chloride is dissolved in hundred gram of water at 293 Kelvin find its concentration at this temperature​

Answer 1

Answer:

Mass of sodium chloride (Solute) = 36gm

Mass of water (solvent) = 100 gm

Mass of solution = 36+100 = 136 gm

Concentration = (Mass of Solute / Mass of Solution) * 100

Concentration = (36/136)*100 = 26.47%

Answer 2

Answer:

$\underline\mathfrak{ANSWER:-}$

➼Be careful about calculating about the mass of solution as you always have to take the sum of masses of solute and solvent to calculate the mass of solution.

➟Mass of sodium chloride (Solute) = 36gm

⟹Mass of water (solvent) = 100 gm

➼Mass of solution = 36+100 = 136 gm

⟹Concentration = (Mass of Solute / Mass of Solution) * 100

∴Concentration = (36/136)*100 = 26.47%
