Hi everyone,

I'm doing this practice question and I'm a bit stuck.. I've got up to working out the moles of X2, which I have calculated to be 14.2/35.5 = 0.4 mols, but I'm confused with how to go about calculating Y2. Please can someone help me out with this.

Thanks in advance! Name:  Screenshot 2019-11-30 at 22.44.32.png
