Molality is greater than molarity because the volume increases when the solute dissolves in water so now the volume of the solution is greater than the mass of the water. If there is very little solute (dilute solution) then it is a good assumption that the volume does not change and molarity equals molality.

Determine the molarity of a saturated NaCl solution at 25°C. Solution. We can see from the curve that about 38 g of NaCl dissolves in 100mL at 25°C. Molarity, M, has the units mol·L-1, so we want to convert 38g ·100mL-1 to mol·L-1. We will use unit analysis to do this. First, however, let's convert mL to L: 38g . 100mL × 10 . 10 = 380g ...
