Im doing the transition work the school set us and i had to find the Mr of CaCo3 and i did 40+ 12 + 16 x 3
but the answer has 40.1 +12+16x3
and i just wondered why it is 40.1 as on my gcse periodic table it just says 40, at alevel is there a more detailed one? Why is it different.

Yes, it is for moles calculations. To make it more precise. They just round it for GCSE usage.

Ah ok thank you ! Will I have to know these off by heart or do they give you a more precise periodic table to use?
