The rules for naming an organic compound regarding punctuation are
a) a comma is put in between two digits (or numbers)
b) a digit and a letter are separated by a hyphan
Example:
3-ethyl-2-methylhexane
2,3,3-trimethylhexane
Lemonade mix and water
Solvent: Water
Solute: Lemonade mix
Calculate first the number of moles of ethylene glycol by dividing the mass by the molar mass.
n = (6.21 g ethylene glycol) / 62.1 g/mol
n = 0.1 mol
Then, calculate the molality by dividing the number of moles by the mass of water (in kg).
m = 0.1 mol/ (0.025 kg) = 4m
Then, use the equation,
Tb,f = Tb,i + (kb)(m)
Substituting the known values,
Tb,f = 100°C + (0.512°C.kg/mol)(4 mol/kg)
<em>Tb,f = 102.048°C</em>
