Question: Would you explain why it comes out to 92/662 instead of 184/662? I thought it would be 184 instead of 92 because it's 4NO 2

Would you explain why it comes out to 92/662 instead of 184/662? I thought it would be 184 instead of 92 because it's 4NO2 not 2NO2

Would you explain why it comes out to 92/662 instead of 184/662?

For the following reaction, how much lead nitrate (Pb(NO3)2) is required to produce 500g of Nitrogen Dioxide (NO2)?[Pb=207;N=14;O=16] Pb(NO3)2NO2+PbO+O2 A. 70 B. 140 C. 35 D. 210 Solution: A Pb(NO3)2NO2+PbO+O22Pb(NO)2=4NO2+2PbO2O22Pb(NO3)2=2(207+2(14+48))=6622NO2=2(14+32)=92Amountofleadnitraterequired=66292(500)=69.570g
