Since ethylene glycol is in excess, it is a solvent and water is a solute.
The molar mass of water is g/mol.
Number of moles of solute moles
Molality is the number of moles of solute in kg of solvent.
g of ethylene glycol corresponds to kg.
Molality m
Total mass of solution g
Density of solution g/mL
Volume of solution ml or 0.394 L
Molarity is the number of moles of solute in L of solution.
Molarity M
