Question

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

Answer 1

$\huge \mathrm{\underline{to \: find}}$

it's concentration at this temperature.

$\huge\mathrm {\underline{solution}}$

$\: \: \: \: \mathrm{mass \: of \: sodium \: chloride = 36 \: g}$

$\: \: \: \: \mathrm{mass \: of \: water = 100 \: g}$

$\: \: \: \: \mathrm{total \: mass \: of \: the \: solution = (36 + 100) g = 136 \: g}$

$\: \: \: \: \mathrm{concentration(maas \: percentage) \: of \: solution = \frac{mass \: of \: NaCI}{mass \: of \: water} \times 100}$

$\: \: \: \: \: \mathrm{ = \frac{36g}{136g} \times 100 = 26.47\%}$
