convert ratio to volum ratio for the orginak distillation mixture? molar ratio = 0.936 cyclohexane : 84 g/mol toluene:92 g/mol ml?
Molar mass of cyclohexane = 84 g/mol
So, 1 mol of cyclohexane = 84 g
Molar mass of toluene = 92 g/mol
So, 1 mol of toluene = 92 g
Molar ratio of cyclohexane to toluene = 0.936 : 1
Suppose, cyclohexane = 0.936 mole and toluene = 1 mole
Now,
1 mol of cyclohexane = 84 g
0.936 mol of cyclohexane = 0.936 x 84 g = 78.624 g
Density of cyclohexane = 0.778 g/mL
Volume = Mass / Density
= 78.624 g / (0.778 g/mL)
= 101.06 mL
and
1 mol of toluene = 92 g
Density of toluene = 0.87 g/mL
Volume = Mass / Density
= 92 g / (0.87 g/mL)
= 105.75 mL
So, volume ratio of cyclohexane to toluene = 101.06 : 105.75
= 0.956
