Look at the formula...#Mg(ClO_4)_2#...

Explanation:

And if you got a mole of this salt, i.e. you got a mass of #223.21*g#...then you gots one mole of magnesium, #24.3*g#, two moles of chlorine ions, #70.9*g#, and EIGHT moles of oxygen, #128*g#...and of course the sum of the atomic/ionic masses....is equal to the given formula mass of the salt....

Can you take it from here if you specify a #3.4*mol# quantity with respect to #Mg(ClO_4)_2#...clearly you gots a mass of #3.4*molxx24.3*g*mol^-1=82.6*g# with respect to magnesium....
