You can take a short cut when dealing with all gases. The short cut is that you can deal directly with volume and not convert to mols. But to complicate matters this is a limiting reagent problem. First convert L ethane to L CO2. L CO2 = 15.9 L C2H6 x ( 4 mols CO2/2 mols C2H6...

268.8 L is 12 moles at STP of O2. Write the balanced reaction for metabolizing sucrose to CO2 and H2O. C12H22O11 + 12 O2 = 12 CO2 + 11 H2O 12 moles of O2 produce an equal number of moles (and an equal volume) of CO2.

consider the equation for the following questions 2C2H6(g) + 7o2(g) 4 CO2(g) +6H2O(g) How many grams of CO2 are produced when 2.00moles of C2H6 react with sufficient oxygen?

chemistry
The equation tells us that 4 mols CO2 will produce 3 mols O2. So, 4 mols CO2 will produce 3 mols O2. 2 mols CO2 will produce 1-1/2 mols O2. 1 mol CO2 will produce 3/4 mol O2. So 2.46 mol CO2 will produce ?? mol O2.

Chemistry help (DrBob222)
First you must determine which is the limiting reagent. C3H8 + 5O2 ==> 3CO2 + 4H2O 3 mol C3H8 x (3 mol CO2/1 mol C3H8) = 3*3/1 = 9 mol CO2 10 mol O2 x (3 mol CO2/5 mol O2) = 10*3/5 = 6 mol CO2 So the limiting reagent is O2. You are reacting 5 mol O2 to produce 6 mols CO2. ...

2C2H6 +7O2 --> 4CO2 + 6H2O since this is already a balanced equation, we can now use their stoich coefficients for the ratios. first, since we need grams of CO2, we find it's molecular mass. from the periodic table, the masses of C and O are C = 12 and O = 16 , thus 1*12 + ...

You may use a shortcut to do these stoichiometry problems when only gases are involved. C3H8 + 5O2 ==> 3CO2 + 4H2O I do these in two parts. 1. How much CO2 is produced if I have 10L C3H8 and all the oxygen I need? That is 10L propane x (3 moles CO2/1 L C3H8) = 10 x 3/1 = 30...

Carbon is a solid. The other two are gasses. You breathe oxygen (O2) in and CO2 out. In combustion, O2 is a reactant and CO2 is a product. That should get you started. Do your own research. It isn't that hard in the internet age

As the volume of a gas is directly related to the number of moles then as 3 moles of O2-> 2 moles of CO2 then 3 volumes of O2 -> 2 volumes of CO2 hence 15 volumes of O2 -> ? volumes of CO2

When only gases are considered, one can take a shortcut and use volume directly without going through mols. 3.2 L O2 x (1 mol CO2/2 mol O2) = 1.6 L CO2 produced.
