Question

Exactly 1 mol Pb(ClO2)2 contains how many moles of Pb , Cl , and O ?

Answer 1

For 1 mole of Lead(II)chlorie we have 1 mole of lead (Pb), 2 moles of Chlorine (Cl) and 4 moles of oxygen (O).

Step-by-step explanation:

Step 1: Data given

Number of moles of Pb(ClO2)2 = 1

Since the oxidation number of Pb is 2+ and the oxidation number of ClO2 is -1

So to bind we should have twice ClO2

1 mole of Pb(ClO2)2 contains 1 mole of Pb; 1*2= 2 moles of Cl and 2*2 = 4 moles of 0.

This means for 1 mole of Lead(II)chlorie we have 1 mole of lead (Pb), 2 moles of Chlorine (Cl) and 4 moles of oxygen (O).
