3. 06 g of a sample of potassium trioxochlorate (V) (KCIO3) was required to make a saturated solution with 10cm3 of water at 25°C. The solubility of the salt at 25°C is [K =39, Cl = 35.5, O = 16]
5.0 moles dm3
3.0 moles dm3
2.5 moles dm3
1.0 molesv
0.5 moles dm3
Correct answer is C
Molar mass of KCIO3 = 122.5 g/mol
3.06g = 10
xg = 1000
frac3.06∗100010
= 306g
Molar conc = fracMassconcMolarmass
Molar conc = frac306122.5
= 2.497mol/dm3
