Question

To make a saturated, 36 g of sodium chloride is dissolved in 100g of water at 293 k. find its concentration at this temperature?​

Answer 1

$\huge\star\sf\underline\pink{Answer:-}$

${\boxed{\sf{ Concentration\:of\: Solution = \dfrac{Mass\:of\: solute}{Mass\:of\: Solution} \times 100}}} \\ \\ \sf{Here,} \\ \\ \sf{Mass\:of\:Solute(Sodium\: Chloride)= 36g} \\ \\ \sf\red{Mass\:of\: solvent (water) = 100g} \\ \\ \sf{So,} \\ \\ \sf{Mass\:of\: solution = Mass\:of\: solute+Mass\:of\: Solvent} \\ \\ \implies\sf{36 + 100} \\ \\ \implies\sf\orange{136\:g}$

$\sf\underline\green{Now ,} \\ \\ {\sf{ Concentration\:of\: Solution = \dfrac{36}{136} \times 100 }} \\ \\ \implies\sf{ \dfrac{3600}{136} } \\ \\ \implies{\boxed{\sf{26.47\: percent(by\:Mass)}}}$

Answer 2

ANSWER

• Mass of solute (sodium chloride) = 36 g

• Mass of solvent (water) = 100 g

• Mass of solution

• = Mass of solute + Mass of solvent

• = 36 g + 100 g = 136 g
