Question

To make a saturated solution 36g of sodium chloride is dissolved in 100g of water at 293k find its concentrations at this temperature .

Answer 1

Heya Sister !!

Here is Your Answer.

Given :
36 g of Sodium Chloride (NaCl) is dissolved in 100 g of water at 293 K.

To find :
Concentration at 293 Kelvin.

Formula Applied :
$Concentration \: Of \: Solution\\ = \frac{Mass \: of \: Solute }{Mass \: of \: Solution} \times 100$
Solution :
Mass of Solution = Mass of Solute + Mass of Solvent
= 36 g + 100 g
= 136 g

Now, Using Formula
$= > \frac{36}{136} \times 100 \\ = > \frac{3600}{136} = 26.47\%$
Hence, The Concentration is 26.47%

Note : The temperature given here does not matter. It is just given to confuse the students.

Hope You Got It

Answer 2

Answer:

$mass \: of \: solute(sodium \: chloride) = \: 36g \\ mass \: of \: solvent(water) = 100g \\ mass \: of \: solution = mass \: of \: solute + mass \: of \: solvent \\ = > 36g + 100g = 136g$
