Homework Statement
A silly sample of a metallic element M, reacts completely with 0.0237 mols of X2 to form 6.78 g MX. What are the identities of M and X?
Homework Equations
mols = grams/molar mass[/B]
The Attempt at a Solution
(kinda have no clue what to do because I'm not sure what to do. There aren't any elements to compare the unknown with !)
Here's the equation i got
M + X2 > MX
balancing it: 2M + X2 > 2MX
6.78g MX * (?)
I honestly don't know what to start with and would appreciate if someone gave me hints ! :(
