Explanation / Answer

n= PV / RT
number of moles of Propane =( .984 x 1) / (0.082 0 x ( 273 + 50))
= 0.03715 moles which weigh 1.56g so 1 mole weighs
1.56 / 0.03715g
= 42.0g

mass of C in 1 mole = 85.7 % of 42 = 36.0 g or 3 moles of C
mass of H = 14.3 % of 42 = 6 g or 6 moles of H

molecular formula of your "propane" is C3H6 .. which is propene !!!
