Question:

What is the mole fraction of solute in a 1 m aqueous solution?

Options:

0.0354

0.0177

0.177

1.770

Correct Answer:

0.0177

Explanation:

1 m solution means that 1 mol of solute is present in 1000 g of water.

Moles of solute = 1

Moles of water = \(\frac{1000}{18}\) = 55.55

Mole fraction of solute = \(\frac{1}{1+55.55}\) = 0.0177
