Find the solubility of KNO3 at 20 degree celcius when the mass of the empty dish is 50g and solution is 65g, while the mass of dish and residue is 54.3g

Solution

Dear student ,

We can express solubility in terms of mass percentage.
Mass of solute = 54.3 - 50 = 4.3 g
Mass of solution = 65 g
$M a s s p e r c e n t a g e = \frac{M a s s o f s o l u t e}{M a s s o f s o l u t i o n} \times 100 M a s s % = \frac{4.3}{65} \times 100 = 6.6 % R e g a r d s$

Dear student ,

We can express solubility in terms of mass percentage.
Mass of solute = 54.3 - 50 = 4.3 g
Mass of solution = 65 g
