Answer :
The molarity of a solution prepared by dissolving the 16. 0 g urea is 0.008 M.
The mass of the Urea = 16 g
The density of the solution = 1.30 g/ml
The volume of the solution = mass / density
The Volume of the solution= 54.6/1.30
The Volume of the solution = 34.125 ml
The molar mass of the urea = 60 g/mol
The number of the moles of the urea = mass / molar mass
The number of the moles of the urea = 16 / 60
The number of the moles urea = 0.266 mol
The molarity of the solution = moles / volumes in in L
The molarity of the solution = = 0.27 / 34.125
The Molarity of the solution = 0.008 M.
