Question

To make a saturated solution, 36 g of sodium chloride is dissolved in 100 g of water at
293 K. Find its concentration at this temperature.

Answer 1

Answer :

• Concentration of solution = 26.47%.

Step-by-step explanation :

Given that,

• Mass of solute (sodium chloride) = 36 g.
• Mass of solvent (water) = 100 g.

$\hrulefill$

$\text{Mass of solution = Mass of solute + Mass of solvent}$

$\implies\rm{36\:g+100\:g=136\:g}$

Now, We know concentration of the solution =

$\rm{\dfrac{Mass\:of\:solute}{Mass\:of\:solution}\times{}100}$

Putting the values, we get,

$\implies\rm{\dfrac{36}{136}\times{}100}$

$\implies\rm{\dfrac{3600}{136}=}\:\bold{26.47\%.}$

Answer 2

Answer:

Concentration of solution=amount of solute×100/amount of solution

36×100/136

3600/136= 26.47%
