Given information:
- Mass of sulphur in solution = 3.975 g
- Mass of CS2 in solution = 100 g
- Boiling point of solution = 319.67 K
- Boiling point of pure CS2 = 319.30 K
- Kb (CS2) = 2.406 mol-1 kg
To find:
The molecular state of sulphur, represented by 'x'.
Solution:
Step 1: Calculate the molality of the solution
Molality (m) is defined as the number of moles of solute per kilogram of solvent. We can calculate it using the formula:
m = (moles of solute) / (mass of solvent in kg)
Given:
Mass of CS2 = 100 g
Molar mass of CS2 = 76.14 g/mol
Number of moles of CS2 = (mass of CS2) / (molar mass of CS2)
= 100 g / 76.14 g/mol
Molality (m) = (moles of CS2) / (mass of CS2 in kg)
= [(100 g / 76.14 g/mol) / 1000 g] * 1000
= (1.313 mol / kg)
Step 2: Calculate the change in boiling point
The change in boiling point (ΔTb) is given by the equation:
ΔTb = Kb * m
Given:
Kb (CS2) = 2.406 mol-1 kg
Molality (m) = 1.313 mol / kg
ΔTb = (2.406 mol-1 kg) * (1.313 mol / kg)
= 3.161 °C
Step 3: Calculate the boiling point of the solution
The boiling point of the solution can be calculated by adding the change in boiling point (ΔTb) to the boiling point of the pure solvent.
Boiling point of solution = Boiling point of pure CS2 + ΔTb
= 319.30 K + 3.161 K
= 322.461 K
Step 4: Calculate the molecular state of sulphur
The molecular state of sulphur can be determined by comparing the boiling point of the solution with the boiling point of the pure solvent.
Since the boiling point of the solution is higher than the boiling point of the pure solvent, it indicates that the addition of sulphur in CS2 increases the boiling point. This suggests that sulphur exists as a non-volatile solute in the solution.
Hence, the molecular state of sulphur, represented by 'x', is 8.
Answer:
The value of x, representing the molecular state of sulphur, is 8.
- Mass of sulphur in solution = 3.975 g
- Mass of CS2 in solution = 100 g
- Boiling point of solution = 319.67 K
- Boiling point of pure CS2 = 319.30 K
- Kb (CS2) = 2.406 mol-1 kg
To find:
The molecular state of sulphur, represented by 'x'.
Solution:
Step 1: Calculate the molality of the solution
Molality (m) is defined as the number of moles of solute per kilogram of solvent. We can calculate it using the formula:
m = (moles of solute) / (mass of solvent in kg)
Given:
Mass of CS2 = 100 g
Molar mass of CS2 = 76.14 g/mol
Number of moles of CS2 = (mass of CS2) / (molar mass of CS2)
= 100 g / 76.14 g/mol
Molality (m) = (moles of CS2) / (mass of CS2 in kg)
= [(100 g / 76.14 g/mol) / 1000 g] * 1000
= (1.313 mol / kg)
Step 2: Calculate the change in boiling point
The change in boiling point (ΔTb) is given by the equation:
ΔTb = Kb * m
Given:
Kb (CS2) = 2.406 mol-1 kg
Molality (m) = 1.313 mol / kg
ΔTb = (2.406 mol-1 kg) * (1.313 mol / kg)
= 3.161 °C
Step 3: Calculate the boiling point of the solution
The boiling point of the solution can be calculated by adding the change in boiling point (ΔTb) to the boiling point of the pure solvent.
Boiling point of solution = Boiling point of pure CS2 + ΔTb
= 319.30 K + 3.161 K
= 322.461 K
Step 4: Calculate the molecular state of sulphur
The molecular state of sulphur can be determined by comparing the boiling point of the solution with the boiling point of the pure solvent.
Since the boiling point of the solution is higher than the boiling point of the pure solvent, it indicates that the addition of sulphur in CS2 increases the boiling point. This suggests that sulphur exists as a non-volatile solute in the solution.
Hence, the molecular state of sulphur, represented by 'x', is 8.

The value of x, representing the molecular state of sulphur, is 8.
