i can never remember the equations for number of atoms or mass of one atom using avogadros constant, i always get it mixed up which one is xMr and xMoles

Just remember mass is mr moles and like if it gives u the avogrados constant that means u do avogrados constant and just practise questions on avogrados constant

What is the equation we have to know for the moles and avogadros constant and number of atoms

Yk the diameters and different names for dust particles and coarse particles do we need to memorise them

i'm praying theres not many I can never remember the equations

I just use triangles with the equations then use mnemonics to remember the equations.

Mr Mass Moles (mr=mass/moles)
Children Make Videos (Concentration=mass/volume or Concentration=moles/volume)
etc

Can't be used for all equations it seems, but that's how I did it for GCSE physics at least.

does anyone know if we need to know the reactivity series (like know the order of it)

you don't need to know it off by heart, but it's best if you do because when there are displacement questions you should be able to identify when something is more reactive than something else ygm

I didn't do triple but 6-6 for combined (chemistry paper 1 2019 probably carried me and that paper was too easy, it felt like doing a foundation tier paper).
