SUMMARY

The discussion focuses on calculating the combustion products of propane (C3H8) when burned with 60% pure oxygen, while considering the collection of gases over water at Standard Ambient Temperature and Pressure (SATP). Participants emphasize the importance of using the correct molecular formula for propane and accounting for water vapor in the calculations. Key equations include the mole calculation formula n = m/M, which is essential for determining the mass and number of moles of the reactants and products. The discussion highlights the need to prepare a table for 1 mole of propane to facilitate these calculations.

Homework Statement


Incomplete combustion of C6H8, set up chart showing number of moles, molar mass and mass
the propane is burned with 60% pure oxygen, the propane is collected over water at SATP

Homework Equations



n=m/M

The Attempt at a Solution


How do I find the mass and number of moles if all I know is molar mass, and amount of propane and 60% pure oxygen?
 
Physics news on Phys.org
Prepare table for 1 mole of propane.
 
It might help with your mole calculations to denote propane as C3H8 rather than C6H8.

I assume the question is asking you to determine the combustion product(s) for a gas mixture that contains 40% propane (collected over water) and 60% oxygen? Do you think that it might be necessary to account for the water vapor in this experiment? Remember that the propane was collected over water at STP. What is the vapor pressure of water at STP and how much of the propane gas is actually water vapor?

Hope it is helpful...
