Question

What is the mole fraction of C12H22011?

Answer 1

The formula is

`\boxed{\sf \chi_A=(\chi_A)/(\chi_A+\chi_B)}`

Denominator will be same for all

Find that

• moles of solution=12+22+11=45

Now

#C

`\\ \rm\Rrightarrow \chi_C=(12)/(45)`

#H

`\\ \rm\Rrightarrow \chi_H=(22)/(45)`

#O

`\\ \rm\Rrightarrow \chi_O=(11)/(45)`
