Hello,

Thanks for checking it. I solved the problem!

Thanks

hey inferno_gogo

So far for A, my aproach has been to mutimply the precentage by the atomic mass, and I get F = 3.57, Cl = 12.27, O = 7.49. From this I can kind of guess that there are 2 F for 5 O, because their mass is relatively close, but I predict 3O for 1 Cl.

Your approach is wrong. You should get the mole ratio instead by dividing the mass ratio with atomic mass, and not multiply. Do try again!


p.s: ok good.
