Does the question specifically say Ag2? or just Ag? there is one mole of Ag2, yet there are 2 moles of Ag.

Not sure if I did the working right.

Moles confuse me a little bit so yup!

B is right

 

[Thief]

B is right

Whoo

But I still don't get the mole bit

So its like Ag2SO4.. theres one mole of Ag2, and with that you use it to calculate the amount of silver?

Well that part depends on personal preference as to whether you go with Ag+ for the calculations or Ag2. Personally if it says calculate the mass of silver ions I prefer to go with just the atoms so i dont have to double anything from the periodic table. Ill latex my working

Ohh never mind it's Year 11, just beat them up so you get first place.

And by beating up, I mean beating them in the HSC.
