Please help me solve and explain the question given.

(Don't copy/spam the answer)

1. If the molar volume of a binary mixture is given by the following empirical expression at 298 K and 1 atm: V[L/mol] = 120x, + 70x2 + (15x, + 8x_)x,x2 (a) Demonstrate the expression for the partial molar volume of component 1 and 2 in terms of x (10 Marks) (b) If the binary mixture contains 70 mol% of component 2, calculate the partial molar volume of both components with justification. (6 Marks) (c) Solve the molar volume for the pure species for both components at 298 K and 1 atm. (4 Marks)
