I am trying to work a solution for this problem, can anyone help me by posting a step by step method, Many thanks

Calculate the vapour pressures of n-hexane and n-decane above a mixture at 25°C containing
2% n-C6H14 + 98% n-C10H22, by volume.
Assume that the densities of pure n-hexane and n-decane are 660 and 730 kg/m  respectively and
that the liquids behave ideally.
