Question

Calulate the amount of carbon dioxed formed when 1mole of carbon reacts with 16g of dioxygen

Answer 1

C. +. O2. =. CO2

C = 1 mole = 12 g
O2 = 1 mole = 32g
CO2 = 1 mole = 44g

it's a easy stoichiometry questions.......

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 .

so when 2 mole of carbon burnt with 16 g of oxygen , it will produce 22*2 g of CO₂

i.e 44g of CO₂ will be generated.
