Q. Describe Molarity and Molality and what is the basic diffrence between Molarity and Molality?
The concentration of a solution is usually expressed as molarity (i.e., M). The higher the molarity of a solution, the more concentrated the solution. For example, a 3 M NaCl solution is more concentrated than a 0.1 M NaCl solution.
Sometimes molality is used to measure concentration. Molality (abbreviated m) is the number of moles of solute dissolved in 1000 grams of solvent.
