The molar volume of a binary liquid mixture of two components: 1 and 2 is described by the expression
V = 20x1 + 50x2 + 6x1x2 [V] = cm/mol
Consider a mixture of 2 moles of component 1 and 4 moles of component 2.
What is the molar volume of pure component 1?
What is the total volume of component 1?
What is the value of the partial molar volume of component 1?
