    I'm presuming that you mean Q3 as Q4 is just multiplying by 10.

    You have 2 copper ions per iodine molecule, so you multiply the answer to Q2 by 2.

    Thanks, I'd already figured it out by the time I saw this. I wasn't sure because for Q2 I had to half my answer to Q1 for the answer so multiplying by 2 would just get me my answer to Q1 again. But turned out to be right
