Vapor Pressure and Partial Pressure and possible relations to pure solutions of these mixtures. Thanks!?

At a certain temperature the vapor pressure of pure hexane, C6H14, is 253 mm Hg and pure octane, C8H18, is 224 mm Hg. What is the partial pressure of each compound and the total pressure of a mixture of 205 g hexane and 180. g octane? Use molar mes with at least as many significant figures as the data given. I need mm Hg for C6H14 and mm Hg for C8H18 and also need mm Hg total.
