Calculating Mass of Compound to Lower Freezing Point
To calculate the mass of a compound that needs to be dissolved in 75g of benzene to lower its freezing point by 0.48K, we can use the formula:
ΔTf = i * Kf * m
Where:
ΔTf = Freezing point depression (0.48K)
i = Van't Hoff factor (assuming it is 1 for this compound)
Kf = Freezing point depression constant for benzene (5.12kg/mol)
m = molality of the solution
Calculating Molality
Molality (m) can be calculated using the formula:
m = (moles of solute) / (mass of solvent in kg)
Calculating Moles of Solute
Moles of solute can be calculated using the formula:
moles = mass / molar mass
Given that the molar mass of the compound is 256g/mol, we can calculate the moles of the compound that need to be dissolved in benzene.
Calculating Mass of Compound
Once we have calculated the moles of the compound, we can then find the mass of the compound that needs to be dissolved by using the formula:
mass = moles * molar mass
By following these steps, you can determine the mass of the compound that needs to be dissolved in 75g of benzene to lower its freezing point by 0.48K.
