Answer to Question #166941 in General Chemistry for Jazmeen

Question

if a normal human breathes at approximately 700 g of carbon dioxide per day how many O2 particles would be needed to produce that much CO2?

Answer 1

Mr(CO₂) -- 700 g

Mr(O₂ ) -- x

x=Mr(O₂ )*700/Mr(CO₂)=32*700/44= 509 g

m(O₂) = 509 g

n(O₂)=509/32=15.9 mol

Answer: 15.9 mole of O₂ would be needed to produce 700 g of carbon dioxide
