A laboratory requires 2000 cm^3 of an antifreeze solution consisting of 30 mol % methanol in water. What volumes of pure methanol and pure water at 25°C must be mixed to form the 2000 cm^3 of antifreeze also at 25C? Assume what an ideal solution is. The partial molar volumes for methanol and water in a 30% mol methanol solution and their molar volumes of pure species both at 25°C are as follows: Methanol Water V₁ - 38.632 cm³/mol V₁ = 40.727 cm³/mol V₂ = 17.765 cm³/mol V₂ = 18. 068 cm³/mol

A laboratory requires 2000 cm^3 of an antifreeze solution consisting of 30 mol% methanol in water. What
volumes of pure methanol and pure water at 25°C must be mixed to form the 2000 cm^3 of antifreeze also
at 25C?
Assume what an ideal solution is. The partial molar volumes for methanol and water in a 30 % mol methanol
solution and their molar volumes of pure species both at 25°C are as follows:
FORMAT
Methanol V. = 38.632 cm'/mol V. = 40. 727 cm³/mol
V. = 17.765 cm/mal Vz = 18 068cm³/mol
