The mass of the carbon dioxide 37.4 g.

A combustion reaction is a type of chemical reaction that occurs when a substance reacts rapidly with oxygen, usually from the air, resulting in the release of heat and light.

The equation of the reaction is;


2 C_4H_(10) +13O_2 ----- > 8 CO_2+10 H_2O

1 mole of butane contains 22.4 L

x moles of butane contains 4.24L

x = 1 * 4.24L/22.4 L

x = 0.189 moles

If 2 moles of butane produces 8 moles of carbon dioxide

0.189 moles of butane produces 0.189 * 8/2

=0.85 moles

Mass of carbon dioxide = 0.85 moles * 44 g/mol

= 37.4 g
