1. Partial pressure is divided according to mole ratio.

Figure out the moles of each, than add to get total moles.

pressuremethane= molesmethane/totalmoles * total pressure

pressurethane= moleethane/totalmoles * total pressure

and so on. until you get the ones you know.
then pressure propane= total pressure-sum of partial pressures ethane, methane, ...
