# Equilibrium Moles Help

1. How would I get the eqm moles for this? I calculated 0.5 mol for 2W and 0.25 mol for X, but my teacher told me it was 1 mol. I don't understand at all and I'd appreciate some help

2W + X <==> 2Y

..3......1...........0
......................0.5

if 0.5 of Y have been formed then 0.5 of W have reacted therefore there are 2.5 of W left.

0.5 of W react with 0.25 of X therefore there are 0.75 of X left at equilibrium.

Yeah, he was wrong. I figured it out eventually. It's just annoying bc i spent hours trying to work out where i went wrong. Thank you!
