4. Consider the following unbalanced chemical equation for the combustion of propane: C3H₂(g) + O₂(g) CO₂(g) + H₂O(g) What volume of oxygen at 25°C and 1.04 atm is needed for the complete combustion of 5.53 grams of propane? 5. Liquid ethanol combusts in oxygen gas to produce carbon dioxide gas and water vapor. The balanced chemical equation for this reaction is: C₂H₂OH(U) + 30₂(g) → 2CO₂(g) + 3H₂O(g) In one experiment, 0.010 L of ethanol reacted with oxygen gas to produce 11.19 L of carbon dioxide gas. What volume of oxygen gas in liters was consumed during the reaction?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
