Empirical formula from masses

  1. Oct 6, 2009 #1
    1. An unknown metam M reacts with sulfur to form a compound with the formula M2S3. If 3.12g of M reacts with 2.88g of S, what re the names of M and M2S3?



    2. 2.88g S ( 1 mol of S/ 32.07 g S) = 0.09 mol of S, thats all i can think of really.



    3. Haven't been able to get one.
