Combustion of ethane (C2H6) gives Carbon dioxide and steam. 4C2H6 --> 4CO2 + 6H2O How many moles of CO2 is produced when 5.75moles of ethane is burned in excess oxygen ?

We use the old Ideal Gas equation to find the moles of gas... n= (PV)/ (RT)= ( (760*mm*Hg)/ (760*mm*Hg*atm^-1)xx0.282*L)/ (0.0821* (L*atm)/ (K*mol)xx288.2*K) =0.0119*mol As a note …

This tells us that if there's 2.272 moles of carbon dioxide molecules, there are also 2.272 individual carbon atoms. Then, we can just find the mass of 2.272 carbon atoms by multiplying …

Once you know the mass of the solute, you can use the density of the solution to find the mass of solvent, which is water. To keep the calculations simple, pick a "1-L" sample of the solution. …

Jul 7, 2017 · Now, you can use the ideal gas law equation to find the number of moles of gas that escaped from the container. The difference between the initial pressure of the gas, let's say P …

Question is: How much NaOH (in grams) is needed to prepare 546 mL of solution with a Ph of 10.00? Am I supposed to find the moles of OH and change that to grams?

Find moles KMnO4 from volume Find moles KMnO4 from volume in LITRES x molarity. Let this be n moles From the balanced equation you know that 4 moles MnO4 1- (aq) react with 3 …

Apr 29, 2016 · You know that your container contains 8 moles of hydrogen gas and 8 moles of oxygen gas. In order to find the limiting reagent, you must determine which reactant will be …

Notice that we have two equations with three unknowns, the mass of the sample, the number of moles it contains, and the fraction that dissociates. In order to be able to calculate the value of …

Oct 19, 2015 · The idea here is that you need to use the ideal gas law to determine how many moles of gas you have in that sample. Once you know how many moles you get in 0.742 g of …
