Question

calculate the amount of co2 produced when 1 mole of carbon is burnt in 16g of dioxygen options are a) 44g b) 22g c) 88g d) 11g

Answer 1

one mole of co2 contains 44 gm of co2 because co2= 12+(2×16)=44

Answer 2

Molecular weight of CO₂

= molecular weight of carbon + molecular weight of dioxygen

= 12g + 32g = 44g

i.e 1 mole of carbon(6g) and 1 mole of dioxygen (32 g ) produce 44 g of carbon dioxide

then 1 mole of carbon burnt with 16 g of oxygen ,

it will produce 44× 16 /32 = 22 g of CO₂ .
