When lead (IV) oxide is heated with hydrogen, the following reaction occurs:
PbO2(s) + 2H2(g) → Pb(s) 2H2O(g)
This reaction can be used to extract lead from its oxide.
Calculate the atom economy to produce lead.
PLS HELP!!!!!!

can anyone pls help I really need the answer to this question
I must tell you that I've beenint this business for over 70 years and I've NEVER heard of atom economy. But I looked it up on Google. You could have done that too and follow their examples.
PbO2(s) + 2H2(g) → Pb(s) 2H2O(g)
molar mass PbO2 = approx 207 + 32 = about 239 but you should confirm with more accuracy.
molar mass 2H2 = 4
atom economy = [(Pb)/(PbO2 + 2H2)] * 100 = ?
atom economy = [(207)/(239 + 4)]*100 = ?
Post your work if you have questions.
