The formula tells you the proportion in mols
2 mols of Cl: 1 mol of Pt
Now use the atomic masses:
Cl: 35.5 g/mol
Pt: 195 g/mol
Then you have these equation:
[2*35.5 g Cl] / 195 g Pt = x / 500 kg Pt
Solve for x.
x = (71 g Cl / 195 g Pt) * 500 kg Pt
x = 182 Kg Cl = 182 kg Cl2.
Answer:
The percent composition of dichlorine heptoxide is 38.76% CI and 61.24% O
Answer:
c) +2 to 0
Explanation:
SO4 has a charge of -2, so the Cu attached to that has to be a +2 since the polyatomic molecule has no overall charge
Cu(s) is a solid metal and they have no charge, therefore it is zero
Copper undergoes Oxidation (gain of electrons)
