5cm³ of a saturated solution of sodium chloride at 30°C gave, on careful evaporation, 1.95g of solid salt. The solubility of sodium chloride at 30°C?

(Na = 23, Cl = 35.5)

You can use this formula

Solute/solvent X 1000/molar mass
1.95/5 X 1000/58.5

=6.67mol dm³

solubility= mass/molar mass multipled by 1000/volume
while we have a mass of 1.95g and a molar mass of 58.5(23+35.5), volume of 5cm³
therefore 1.95/58.5 × 1000/5
=0.03×200
=6.67dm³~

oh!
God bless y'all for a quick reminder of this formula.🤗

Compared to that stuff they were solving there

You can use this formula

Solubility=solute. 1000
------------ X -----------
Solvent. Molar mass
