Is there any difference between molarity and molarity solitions? If so what are the differences?
Answer:
The molarity of a solution is defined as the number of moles of solute per liter of solution.
Molality is defined as the numbers of moles of solute per Kg of solvent
Example:
You have a soltion which contains 410.3 g H2SO4 per liter of solution. If density of the solution is 1.243 g/mL , what is the molality and the molarity of the solution ?
1 L of solution weights 1243 g
We are told that 410.3 g of this is H2SO4 , so the rest of the weight (1243 - 410 = 833 g ) must be water.
410.3 g / 98.078 g/mol = 4.183 moles
Molarity = 4.183 / 1 L = 4.183 M
molality = 4.183 / 0.833 Kg = 5.02 m
