Question

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 3.50 moles of magnesium

perchlorate. Mg(C104)2.
Express the number of moles of Mg, Cl, and O atoms numerically, separated by commas.

Answer 1

`n_(Mg)=3.50molMg\\\\ n_(Cl)=7.00molCl\\\\n_O=28.0molO`

Step-by-step explanation:

Hello there!

In this case, according to the given information it turns out possible for us to realize that one mole of the given compound, Mg(ClO₄)₂, has one mole of Mg, two moles of Cl and eight moles of O; thus, we proceed as follows:

`n_(Mg)=3.50molMg(ClO_4)_2*(1molMg)/(1molMg(ClO_4)_2)=3.50molMg\\\\ n_(Cl)=3.50molMg(ClO_4)_2*(2molCl)/(1molMg(ClO_4)_2)=7.00molCl\\\\n_O=3.50molMg(ClO_4)_2*(8molO)/(1molMg(ClO_4)_2)=28.0molO`
