here's a question from my recent chem exam that i don't know how to approach:

a sample of 0.600 mol of a metal M reacts completely with excess fluorine to form 46.8 g MF2

a) how many moles of F are in the sample of the compound that forms?

b) how many grams of M are in this sample of MF2?

c) what element is represented by the symbol M?

i started to try to write a balanced equation for this but i'm not sure if the coeffecients would be right...

any help? thanks!

the balanced equation is just going to be M + F2 -> MF2

so there would be 1.2 mol of F in the compound right
