Answer:
of are found in 39.5 grams of .
Explanation:
Atomic weights : P= 31, F= 19,
molar mass of = 1 atomic weight of P+ 5 atomic weight of
F= 31+5 19
= 31+95
=126 g/mole
moles in 39.5 gm of
=
=
=0.3134 moles
1 mole of any substance contains
0.3131 moles contains 0.3134
Therefore, of are found in 39.5 grams of .
