Why molality preferred over molarity |
| Answer» Molarity depends upon volume and we know that volume changes with temperature. So molarity differs with temperature wheras molality is not variable, hence molality is preferred over molarity<br>Because molalty have mole/weight(kg) .weight never change by temp. ,Humidity ,pressure etc but volume will be change. Volume in molarty<br>because their is no effect of temperature in molality. It does not change with temp. as molality is equal to no. Of moles of solute /mass of the solvent in kg. Where as molarity is change because molarity is depend upon volume of solution (molarity is equal to no. Of moles of solute /volume of solution in litre ).volume is change with temp. | |
