A student dissolves 15.g of styrene in 250.mL of a solvent with a density of 0.88g/mL. The student notices that the volume of th

matrenka [14]

Answer: The molarity and molality of styrene solution is 0.58 M and 0.66 m respectively

Explanation:

To calculate the mass of solvent, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of solvent = 0.88 g/mL

Volume of solvent = 250. mL

Putting values in above equation, we get:

$0.88g/mL=\frac{\text{Mass of solvent}}{250mL}\\\\\text{Mass of solvent}=(0.88g/mL\times 250mL)=220g$

Calculating the molarity of solution:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

Given mass of styrene = 15. g

Molar mass of styrene = 104.15 g/mol

Volume of solution (solvent) = 250. mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{15\times 1000}{104.15\times 250}\\\\\text{Molarity of solution}=0.576M=0.58M$

Calculating the molality of solution:

To calculate the molality of solution, we use the equation:

$Molality=\frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ in grams}}$

Where,

$m_{solute}$ = Given mass of solute (styrene) = 15 g

$M_{solute}$ = Molar mass of solute (styrene) = 104.15 g/mol

$W_{solvent}$ = Mass of solvent = 220 g

Putting values in above equation, we get:

$\text{Molality of styrene solution}=\frac{15\times 1000}{104.15\times 220}\\\\\text{Molality of styrene solution}=0.655m=0.66m$

Hence, the molarity and molality of styrene solution is 0.58 M and 0.66 m respectively.
