Ethanol (C2H6O) is combusted with oxygen to produce carbon dioxide and wateraccording to the following reaction:
C2H6O + 3O2 -----> 2H2O + 3CO2
If 50g of ethanol is combusted, determine the volume of carbon dioxide that will be produced if the temperature is 25oC and the pressure is 100kPa.
1. mols ethanol = grams/molar mass
2. Use the coefficients in the balanced equation to convert mols ethanol to mols CO2.
3. Use PV = nRT and substitute n = mols and the other conditions and solve for volume in L. Don't forget T must be in kelvin.
