First you should know that there is seven oxygen atoms in one Mn2O7
So
2.00 moles of Mn2O7 contain 14.00 moles of oxygen...
Then you multiply this no. with Avagadro no....
from formula
Number of moles= no. of particles/avagadro's no..
14.00×6.02×10²³=84.28 atoms of oxygen...
A) The alkali metal atoms forms a +1 ion, while the alkaline eaeth metal atom forms a +2 ion.
It is tasteless and colorless.
