Define molarity and molality |
|
Answer» Molality:-Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent. This contrasts with the DEFINITION of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg.Hint: Molarity is the ratio of moles of solutes in per litre of solution while the molality is the ratio of moles of solutes in per kilogram of solvent. Molarity is generally used to calculate the volume of solvent or the amount of solute.Molarity is the ratio of the moles of a solute to the TOTAL liters of a solution. The solution includes both the solute and the solvent. Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.Molality is defined as the number of moles of solute present in 1000 gm of the solvent. Example: Calculate the molality of a solution PREPARED from 29.22 grams of NaCl in 2.00 kg of water.Explanation:i HOPE you got the best ANSWER |
