Question

Mole fraction of the solute in a 1.00

molar aqueous solution is ……

(a) 0.0177 (b) 0.0344

(c) 1.7700 (d) 0.1770
hiii.​

Answer 1

Answer:

a) 0.0177

Explanation:

1.00 molal solution means 1 mole of solute in 1 kg (or 1000 g) of water.

Number of moles of solute =1

Number of moles of solvent =

18

1000

=55.55

Mole fraction of Solute =

1+55.55

1

=0.01768

Hence, the correct option is A
