Question

calculate the mole fraction of glucose in the solution containing 20g of glucose in 80g of water​

Answer 1

Answer:

Suppose we have 100 g solution. Then in the solution there is 20 g glucose and 80 g water.

Moles of glucose=20 g180 g/mol=19 mol

Moles of water=80 g18 g/mol=409 mol

Total moles=19 mol+409 mol=419 mol

Mole fraction of glucose=19mol419mol=0.024
