Determine the concentration of a solution (in % by mass, % by volume, % by mass
volume, molarity, molality and ppm) containing 5 grams of NaCI and 50 ml of water.(p of NaCl = 2.1 g/ml,p of water = 1g/ml).What is the mole fraction of NaCI in the solution?
Given grams of and of water
Concentration of Solution in molarity
Concentration of Solution in molality
We know that density of Water is .
So, mass of Water present in solution density volume
Hence moles of water
Mole fraction of in solution
