Asolution of iron (iii) chloride is made to be 1.541 m, and 1.457 m in water. calculate the density of the solution and percent by mass iron (iii) chloride.

Given that the molality of the Iron(III) chloride solution = 1.541 mol /kg water

1.541 mol is present per L solution

Calculating mass of from 1.541 mol:

Mass of solvent = 1 kg

Total mass of the solution = 1000 g + 249.95 g = 1249.95 g solution

Density of the solution =  

Molarity of the solution = 1.457 mol/L solution

Calculating mass of   from 1.457 mol:

Volume of the solution = 1 L *

Mass of solution =

Mass percentage of in the solution =

Therefore density of the solution is 1.25 g/mL

Mass percent of the solution is 18.9 %

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
