Calculate the mass of acetylene that releases 2.6 moles of carbon dioxide when burned.

The oxidation reaction of acetylene with oxygen is described by the following chemical reaction equation:

2C2H2 + 5O2 = 4CO2 + 2H2O;

2 moles of acetylene are reacted with 5 moles of oxygen. This will synthesize 4 moles of carbon dioxide and 2 moles of water.

To get 2.6 mol of carbon dioxide, it is necessary to oxidize 1.3 mol of acetylene.

Let’s calculate its weight.

To do this, we multiply the amount of the substance by the weight of 1 mole of the substance.

M C2H2 = 12 x 2 + 2 = 26 grams / mol;

m C2H2 = 1.3 x 26 = 33.80 mol;
