This is an impossible formula. Pretend it is real.If you had 1 mol of Cr7(PO4)3 how many moles of Cr would there be?This is an impossible formula. Pretend it is real.If you had 1 mol of Mn6(ClO4)3 how many moles of O would there be?

Answer :

Answer:

7 moles of Cr

Explanations:

Given that there is 1 mole of he compound Cr7(PO4)3, the 1 mole of the compound is composed of 12moles of oxygen, 3 moles of phosphorous and 7 moles of chromium.

Hence we can conclude that there will be 7 moles of Cr in 1 mole of Cr7(PO4)3
