20(C4H6BaO4) 15*20 = 300 atoms
15
In total Their Are 15 Atoms IN 3cH4
there are 15 atoms
6 times with 12 remaining
w + 15 = 102 Subtract 15 from both sides w + 15 - 15 = 102 - 15 Combine and clean up. w = 87 ■
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
The no of atoms are 15 x 6.023 x 1023 .
Approx. 9.1024 atoms.
The answer is 15 carbon atoms.

Ca3(PO4 )2 That is 3+(2(2)+4(2)) = 15 so, 15 atoms
The sum you want is 102 x 0.15
