Which of the following is the correct set-up for the problem: How many grams of water will be produced from 3.2 moles of oxygen
suter [353]

Option C is the correct set of the problem for mass of water produced by 3.2 moles of oxygen and an excess ethene.

<h3>Reaction between oxygen and ethene</h3>

Ethene (C2H4) burns in the presence of oxygen (O2) to form carbon dioxide (CO2) and water (H2O) along with the evolution of heat and light.

C₂H₄  + 3O₂   ----- > 2CO₂ + 2H₂O

from the equation above;

3 moles of O₂ ---------> 2(18 g) of water

3.5 moles of O₂ ----------> x

x = 3.2 \times [\frac{2 \ moles \ H_2O}{3 \ moles \ O_2}  ] \times[ \frac{18.02 \ g \ H_2O}{1 \ mole \ H_2O} ]

Thus, option C is the correct set of the problem for mass of water produced by 3.2 moles of oxygen and an excess ethene.
