Asolution of a sugar with the chemical formula (c12h22o11) is prepared by dissolving 8.45 g in 250.0 ml of water at 25 c. the density of this solution is 1.21 g/cm3. calculate the concentration in terms of molarity, molality, weight percent and ppm. assume that the volume of the solution is equal to the volume of the solvent. show your work.

Answer : The molarity, molality, weight percent and ppm are, 0.0987 mole/L, 0.0839 mole/Kg, 2.79% and 27933.8843 respectively.

Solution : Given,

Mass of solute = 8.45 g

Molar mass of solute = 342.3 g/mole

Volume of solvent (water) = volume of solution = 250 ml

Density of solution =

Calculation for molarity

Now we have to calculate the mass of solution.

Now we have to calculate the mass of solvent.

Calculation for molality

Calculation for weight percent

Calculation for ppm

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
