Answer :
The number of moles of magnesium, chlorine, and oxygen atoms in 2.70 moles of magnesium perchlorate is 2.70, 5.40, 21.60.
The formula of the compound is Mg(ClO4)2.
From the formula, we can see that 1 molecule of Mg(ClO4)2 contains 1 atom of Mg, 2 atoms of Cl and 8 atoms of O.
So 2.70 mol Mg(ClO4)2 contains
1 * 2.70 mol Mg = 2.70 mol Mg
2 * 2.70 mol Cl = 5.40 mol Cl
8 * 2.70 mol O = 21.60 mol O
So, the required answer is 2.70, 5.40, 21.60.
Therefore, the number of moles of magnesium, chlorine, and oxygen atoms in 2.70 moles of magnesium perchlorate is 2.70, 5.40, 21.60.
