At 25C and atmospheric pressure the volume change of mixing of binary liquid mixtures of species 1

Question:

At 25°C and atmospheric pressure the volume change of mixing of binary liquid mixtures of species 1 and 2 is given by the equation
ΔV = x₁ x₂ (45x₁  + 25x₂)
where ΔV is in cm³·mol⁻¹. At these conditions, V₁ = 110 and V₂ = 90 cm³·mol⁻¹. Determine the partial molar volumes V̅₁ and V̅₂ in a mixture containing 40-mol-% of species 1 at the given conditions.
