Question

When 5 grams of glucose is dissolved in 40 gram of water, calculate mole fraction of glucose

Answer 1

Moles of glucose = 5 g / (180 g/mol)
= (1 / 36) mol

Moles of water = 40 g / (18 g/mol)
= (20 / 9) mol

Mole fraction of glucose = Moles of glucose / Total moles
= (1 / 36) / [1/36 + 20/9]
= 0.012

∴ Mole fraction of glucose in given solution is 0.012
