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

How many grams of hexan-1-ol did you all get? And what did you put for the fertilisation question about mgNo3?

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
