12 g of solid protassium chlorate (KCIO) were added to 40 g of water and heated to dissolve all the solid. As the solution cools, crystals of potassium chlorate at 66 oC. The solubility of potassium chlorate at 66 oC is therefore?

solubility = solute/solvent x 100g

How possible is this ? Solubility=(mass/mm)x(1000/volume). I see no correlation

mass of solute = 12g
mass of solvent = 40g(40cm3) since water has a density of 1g/cm3
in dm3 = 40/1000 = 0.04dm3
Solubility = 12g/0.04dm3 = 300g/dm3
NO OPTION IS CORRECT
NO OPTION IS CORRECT
Answer couldn't have been in mol/dm3 since the atomic masses of K, Cl and O weren't given

Could u pls how workings?

Solubility is M/MM x 1000/V.
Mm of KClO = 39+ 35.5 + 16 =90.5
Volume= 40cm^3
So, Solubility=(12/90.5)x(1000/40)= 3.315g/dm^3
The answer isn't there

Absolutely correct "E"
this is calculation on solubility in grams of solvent per 100g.
Molarity is calculated in volume per 1000. CHECK THE TWO FORMULA
