What is the molality of a solution consisting of 4.45 ml of carbon tetrachloride (ccl4; d = 1.59 g/ml) in 85.1 ml of methylene chloride (ch2cl2; d = 1.33 g/ml)?

0.44 mol/kg

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

= weight of solvent in g

Mass of solute

moles of solute =

Mass of solvent

Molality =

Thus molality of solution will be 0.44 mol/kg.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
