Question

In one molal solution that contains 0.5 mole of a solute, there is ______.

Options

• 500 g of solvent

• 100 ml of solvent

• 1000 g of solvent

• 500 ml of solvent

Answer 1

In one molal solution that contains 0.5 mole of a solute, there is 500 g of solvent.

Explanation:

Given: Molality = 1 mol/kg

Moles of solute = 0.5 mol

`"Molality (m)" = "moles of solute"/"mass of solvent in kg"`

`1 = 0.5/"mass of solvent (kg)"`

Mass of solvent = 0.5 Kg 

= 500 g
