Homework Help: Chemistry

Posted by Chopsticks on Wednesday, January 21, 2009 at 6:04pm.

Determine the simplest formula for compounds that have the following analyses. The data may not be exact.

A.
28.5% iron, 48.6% O, 22.9% S

This is what I did:
28.5g Fe 1 mole Fe/55.847g = .51 mole
48.6g O 1 mole O/15.999g = 3.04 mole
22.9g S 1 mole S/32.064g = .71 mole

(Fe1.0 O6.0 S1.4)5 = Fe5 O30 S7

is that right? can you please help me check my answer?
