Solution

The correct option is A $1000 g$ of the solvent
Molality is the number of moles of solute dissolved in 1000 grams of solvent.
So 1 molalal solution contains one mole of solute in 1000 grams of solvent.
$1 M = \frac{1 m o l e}{1 l i t e r}$ .
Hence option A is correct.

A scene in a fantasy chemistry lab.
Faraday was measuring the concentration of different solutes in different solutions. But he forgot the exact formula for Molarity, Molality and Normality. He decides to ask his colleagues.

Davy: ''Molarity is the number of moles of solute dissolved in 1 litre of solvent.''
Boyle: ''Molality is the number of moles of solute dissolved in 1 kg of solvent.''
Cavendish: ''Normality is the number of equivalents of solute dissolved in 1 litre of solution.''
