Explanation / Answer

1 mole P4O10 contains 4 moles P, so

83.5 moles P4O10 contain: 4*83.5 = 334 moles P

In C3H8 molecule, for every 8 H-atoms we have 3 C-atoms

So, for 7.52*1024 H-atoms, we have: (3/8)*7.52*1024 = 2.82*1024 C-atoms

Moles of sample present = 2.82*1024 / (3*6.023*1023) = 1.56 moles

MW of C3H8 = 44 g

So, mass of sample = 44*1.56 = 68.64 g
