Question

A molal solution is one that contains 1 mol of a solute in

• A. 1000 g of solvent
• B. 1 L of solvent
• C. 1 L of solution
• D. 22.4 L of solution

Answer 1

The correct option is A 1000 g of solvent

The number of moles of the solute present per kilogram of the solvent is known as its molality.
$m=\frac{W_{solute}}{M{w}_{solute}}\times \frac{1}{W_{solventinkg}}=\frac{W_{solute}}{M{w}_{solute}}\times \frac{1}{W_{solventing}}\times 1000$
