When 50cm2 of a saturated solution of sugar of ... - JAMB Chemistry 2006 Question
When 50cm2 of a saturated solution of sugar of molar mass 342 g at 40oC was evaporated to dryness, 34.2g of dry solid was obtained. The solubility of sugar at 40oC is
A
2.0 mol dm-3
B
3.5 mol dm-3
C
7.0 mol dm-3
D
10.0 mol dm-3
correct option: a
solubility = mole * 1000cm3/volume
mass/molar mass * 1000cm3/volume
= 34.2/342 * 1000cm3/50cm3-3
mass/molar mass * 1000cm3/volume
= 34.2/342 * 1000cm3/50cm3-3
