Acetylene gas, C2H2, reacts with oxygen according to the following equation. If 52.0 g of acetylene react completely with sufficient oxygen, how many grams of carbon dioxide are produced

176 g of CO₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O

Next, we shall determine the mass of C₂H₂ that reacted and the mass of CO₂ produced from the balanced equation.

This is illustrated below:

Molar mass of C₂H₂ = (2×12) + (2×1)

= 24 + 2 = 26 g/mol

Mass of C₂H₂ from the balanced equation = 2 × 26 = 52 g

Molar mass of CO₂ = 12 + (2×16)

= 12 + 32 = 44 g/mol

Mass of CO₂ from the balanced equation = 4 × 44 = 176 g

From the calculations made above,

52 g of C₂H₂ reacted to produce 176 g of CO₂.
