Question

5 moles of glucose is dissolved in 20 moles of water, Calculate mole fraction of glucose.​

Answer 1

Answer:

1/4

Explanation:

The answer is simple we already know that 20 = 100%,Thus half of 20 which is 10 the percentage would be 50% and 5 = 25% ,100÷25=4 meaning It is 1/4 of 20 Thus The answer is 1/4. May this Help you!

Answer 2

Answer:

Solution contains glucose C6H12O6and water

Molar mass of glucose = 180 g

Molar mass of water= 18 g

mole fraction of glucose = moles of glucose/(moles of gluocose+moles of water)

moles of gluocose, n=mass/molar mass=

5/180= 0.027

moles of water, n=mass/molar mass = 20/18 = 1.11

mole fraction of glucose

= 0.027/(0.027+1.11)

I don't know beyond that.??
