Question

What is mole fraction of solute in 1.00 m aqueous solution?
(a) 0.0354
(b) 0.0177
(c) 0.177
(d) 1.770

Answer 1

Answer:

(B) 0.0177

Explanation:

1.00 m aqueous solution means 1 mole of solute in 1 kg of water.

1 kg of water corresponds to

18

1000

=55.56 moles.

The mole fraction of solute is

1+55.56

1

=0.0177.

Hence, the correct option is B.
