(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

mols = grams/molar mass

3. 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 ! :(
