STANDARD Chemistry Molality MCQ Question
What will be the molality of the solution containing 18.25 g of HCl gas in 500 g of water?
0.1 m
1 M
0.5 m
1 m
Correct Answer
Detailed Explanation
Molality is calculated using the formula: Molality (m) = (No. of moles of solute) / (Mass of solvent in kg). Given that the mass of HCl is 18.25 g and the molar mass of HCl is 36.5 g mol⁻¹, the molality is 1 m.
