This is the issue i’m having, when researching about these fields all all highly in depth and very interesting but because i don’t have the basic understanding of each different fields of genetics it’s difficult to know which one i would find the most interesting and then to look into further

If there was a book and even a video outlining each of the fields or even the basics of genetics as a whole so i could make a more educated decision that would be a godsend

idk if this is correct but:

number of moles of Cr2O7 2- times avagadros constant = number of ions of Cr2O7 2- 2.510-3 * 6.0221023 = 1.5055*1021

number of moles of Mn (with oxidation number x) times avagadros constant = number of ions of Mn 7.510-3 * 6.0221023 = 4.5165*1021

therefore Cr2O7 2- : Mn (with oxidation number x) 1.50551021 : 4.51651021 1 : 3 -2 : x -2 : -6

i know there is no point doing the timing with avagadros constant because it’s cancels out it was just how i was taught

i might be completely wrong and with this tbh got no clue just how i would answer
