Question

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

Answer 1

Answer:

Mass of solute = 36 g

Mass of solvent = 100g

Mass of solution = 100 + 36

= 136g

Concentration of solution = (Mass of solute / Mass of solution ) x100

= (36/136) x 100

= 26.47%

$\huge\mathbf{\underline{\red{Answer:}}}$

$\displaystyle{\sf{Mass\:of\:sodium\:chloride\:=\:36g}}$

$\displaystyle{\sf{Mass\:of\:water\:=\:100g}}$

$\displaystyle{\sf{Mass\:of\:solution\:=\:100+36=136g}}$

$\displaystyle{\sf{Concentration\:of\:solution\:at\:293K}}$

:$\implies$${\boxed{\sf{\orange{= \dfrac{36}{136} \times 100 = 26.47\% }}}}$
