Question

what will be the total mole fraction of solution and mole fraction of each component after dissolving 34.2 g sucrose and 18 gram glucose into 225 gram water​

Answer 1

Explanation:

MOLES OF SUCROSE = 34.2/342 = 0.1 moles

MOLES OF GLUCOSE = 18/180 = 0.1 moles

MOLES OF WATER = 225/18 = 12.5 moles

MOLE FRACTION OF SUCROSE = 0.1/(0.1+0.1+12.5) = 0.0078

MOLE FRACTION OF GLUCOSE = 0.1/(0.1+0.1+12.5) = 0.0078

MOLE FRACTION OF WATER = 12.5/(0.1+0.1+12.5) = 0.984
