Ans: Relationship between molarity,
molality and density:
Density = Molarity/Molality
Given Molarity = 12.5 mol/vol(cc) and
Molality = 11.5 mol/mass (grams)
Density = [12.5 mol/vol(cc)] /[11.5 mol/
mass (grams)]
Density = 1.087 grams/cc
molality and density:
Density = Molarity/Molality
Given Molarity = 12.5 mol/vol(cc) and
Molality = 11.5 mol/mass (grams)
Density = [12.5 mol/vol(cc)] /[11.5 mol/
mass (grams)]
Density = 1.087 grams/cc
