What is the mole fraction of the solute in a 1.00 m aqueous solution ?

A

0.0354

B

0.0177

C

`0.177`

D

`1.770`

Text Solution

Verified by Experts

The correct Answer is:
B
1.00 m solution means that 1 mole of solute is present in 100 g of water
Moles of solute = 1
Moles of water `= (1000)/(18) = 55.55`
Mole fraction of solute `= (1)/(1+55.55) = 0.0177`
