0.080 m FeCl3
find the boiling point it.
so i did ( 0.080)(.51)(4)+100
and i got 100.16 whyy is that wrong?
100.16 looks ok to me.
To find the boiling point of a solution, you cannot simply add the values together as you have done. The equation you used, (0.080)(0.51)(4) + 100, is incorrect for calculating the boiling point.
To determine the boiling point of a solution, you need to consider its colligative properties, specifically the boiling point elevation. The boiling point elevation is dependent on the molality of the solute.
The formula for calculating the boiling point elevation (∆Tb) is:
∆Tb = Kb × m × i
Where:
- ∆Tb is the boiling point elevation
- Kb is the molal boiling point constant (specific to the solvent)
- m is the molality of the solute (in mol solute/kg solvent)
- i is the van't Hoff factor (the number of particles the solute dissociates into when dissolved)
In this case, FeCl3 is the solute. FeCl3 dissociates into four particles in water (Fe3+, 3Cl-), so the van't Hoff factor (i) is 4.
To find the boiling point elevation, you would need the molal boiling point constant (Kb) for water and the molality (m) of the solution. Once you have these values, you can substitute them into the equation to find the boiling point elevation (∆Tb).
Since you have only provided the concentration (0.080 m), we need additional information to calculate the boiling point elevation and subsequently determine the boiling point of the solution.
If you have the necessary additional information, please provide it so that I can assist you further in finding the correct boiling point.
