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 =
<u>Calculation for molarity
</u>
Now we have to calculate the mass of solution.
Now we have to calculate the mass of solvent.
<u>Calculation for molality
</u>
<u>Calculation for weight percent</u>
<u>Calculation for ppm</u>
