hi,

Can you please double check to see if i have got this right?

Is the empirical formual for oxide of arsenic As2O5?

Cheers ;)

Arsenic forms two oxides with oxygen. One is As2O5, the other is As2O3. I'm glad you posted today; please tell your friend you were talking with yesterday (from Scotland) that the data he/she looked at on the other answers, and which he/she was copying to you, shows the formula to be As2O3 and NOT As3O2. I posted a response to that but I'm not sure he/she will see it.
With regard to your problem, if you will post your numbers (mass oxide, mass metal, etc) I can check it in minutes. Thanks.
