Question

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

Answer 1

Answer:

26.47

Explanation:

Mass of sodium chloride (Solute) = 36gm

Mass of water (solvent) = 100 gm

Mass of solution = 36+100

∴ Mass of solution = 136 gm

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

Concentration = (36/136) × 100

Concentration = 26.47%

Answer 2

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

${ \underline{ \boxed{ \large{ \bf{ \gray{Answer}}}}}}$

Mass of solvent(sodium chloride) = 36g

Mass of solvent (water) = 100g

Then,mass of solution = Mass of solute + Mass of solvent.

=(36 + 100)g

=136g

Therefore,concentration(Mass by Mass percentage) of the solution.

${ \bf{ = \frac{Mass \: of \: solute}{Mass \: of \: solvent} \times 100\%}}$

${ \bf{ \boxed{ = \frac{36}{136} \times 100\% = 26.4\%}}}$
