Question

To preapre a saturated solution of common salt, 36 g of sodium chloride
are dissolved in 100 g of water at 293 K. Find its concentration at this
temperature.

​

Answer 1

Answer:

Explanation:

= 36 ,

= 100 ,

= 100 + 36 ,

136 .

=( / )*100,

(36/136)*100,

26.47%.

.

Answer 2

Answer:

26.47 %  

Explanation:

mass of sodium chloride (solute) =36 g

mass of water (solvent) = 100 g

mass of solution = 100 + 36 g = 136 g

concentration of a solution = mass of solute/ mass of solution  * 100

                                            = 36  / 136  * 100

                                            =   26.47 %
