What is the molarity when 2 mol solute is dissolved to make 1 L of solution?
Advertisement
Answer and explanation
Correct answer: 2 M
Molarity is defined as moles of solute per litre of final solution. Applying M = n/V gives M = 2 mol/1 L = 2 mol L⁻¹, which is written as 2 M. Thus option A is correct. Option B would incorrectly ignore one mole, option C would reverse the ratio, and option D has no basis in the given data.
