What did you get for X in SrCl2 x H2O? I got 5.8 when not rounding any other calcs but 5.9 when rounding. I went with 5.8 in the end. Overall I felt like it was a good paper, the 6 markers were nice too

Yeah at first I rounded 5.9 to 6 but then saw the question asked for 2sf so I assumed you were supposed to get a decimal

Why did you divide by 2?
Don’t you just divide the mass by 18 then by the smallest one to get the ratio

I got 86.1 but I doubt it’s right but I got it right when I put in the formula . But I used trial and error as my last minute resort 😂😂😂😂

I had no idea. Not something I revised, so I couldn't answer it. I ran out of time to look at it properly to guess.

Wasn't it about definition of an isotope? There was the isotope abundance question on Sr as well.
