If anyone could help me see where I'm messing up, I'd greatly appreciate it. Thank you.
Determine the empirical formula for compouds that have the following analyses:
60.9% As and 31.9% S
I have the answer key for this problem, I just have to show the correct work to get to there. The problem is, I do the problem, but don't come up with the correct answer.
60.9 g As (1 mol) = .813 = 1
74.92 .813
39.1 g S (1 mol) = 1.220= 2
32.06 .813
*Note when I used the numbers 1.220 and .833 I didn't round them off there. I punched the full answers in my calculator, but for writing purposes I just wrote them down as .833, etc.
I end up getting as my final answer: AsS2
when the answer should be: As2S3.
If anyone can tell me where I'm off, I'd appreciate it a lot. Thanks.
