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

A

1.77

B

0.0354

C

0.0177

D

0.177

Text Solution

Verified by Experts

The correct Answer is:
C
1 molal aqueous solution means 1 mole of solute is present in 1000 g of water.
`:. X_("solute") = 1/(1+1000/18) = 1/(56.5) = 0.0177`
