Question

what is the mass Percent of glucose in water when the mole fraction of glucose is 0.01​

Answer 1

Answer:

Correct option is

A

0.01

Explanation:

Mole fraction =

No. of moles of solution

No. of moles of glucose

Molecular mass of Glucose = 180g/mole

No. of moles of Glucose =

180

10

=0.0555 moles

Molecular mass of water = 18g/mole

No. of moles of water =

18

90

=5 moles

Mole fraction =

0.0555+5

0.0555

= 0.01 moles
