QUESTION:

Using the equation in Sample 6.7, calculate the number of moles of oxygen that must react to produce 0.756 mole of water.Sample 6.7Propane gas (C3H8), a fuel used in camp stoves, soldering torches, and specially equipped automobiles, reacts with oxygen to produce carbon dioxide, water, and energy. How many moles of CO2 can be produced when 2.25 moles of C3H8 react? PropaneSolutionStep 1 State the given and needed quantities.Analyze the 2 Write a plan to convert the given to the needed quantity (moles or grams). Step 3 Use coefficients to write mole?mole factors; write molar mass factors if needed. Step 4 Set up the problem to give the needed quantity (moles or grams). The answer is given with three SFs because the given quantity, 2.25 moles of C3H8, has three SFs. The values in the mole?mole factor are exact.
