Question and answer
If 5.0 moles of propane react, how many molecules of water will be formed? A. B. C. D.
Propane is C3H8 The balanced equation is: C3H8 + 5 O2 - > 3 CO2 + 4 H2O From the balanced equation you can see that for each mole of C3H8 you obtain 4 moles of H2O. moles H2O = 5.0 moles C3H8(4 moles H2O/1 mole C3H8) = 20 moles H2O [ formed Use Avogadro's number to find the number of molecules. molecules H2O = 20 moles H2O(6.02 x 10^23 molecules/1 mole) = 1.20 x 10^25 H2O molecules ]

When glucose is consumed by humans, it reacts with oxygen in the body to produce carbon dioxide, water, and energy. How many grams of carbon dioxide would be produced if 45 grams of glucose completely react with oxygen? Round to the nearest whole number. Don't forget the units.
Weegy: It would be 66 g of carbon dioxide. moles glucose = 45 g/ 180 g/mol=0.25 moles CO2 = 0.25 x 6 =1.5 mass CO2 = 1.5 mol x 44 g/mol=66 g (More)
