## 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 ! :(
