If 5.0 moles of C3H8 react, how many molecules of water are formed?
The reaction of propane with oxygen is C3H8 + 5 O2 —-> 3 CO2 + 4 H2O
Therefore for every atom of C3H8, four atoms of water are produced.
Therefore 5 moles of C3H8, 5 x 4 moles of water are produced
On the basis of Avogadro’s constant, 1 mole of water contains 6.02214129 x 10^23 molecules
Therefore 5 x 4 = 20 moles
20 moles of water contains 20 x 6.02214129 x 10^23 molecules
= 120.4428158 x 10^23 = 1.204428158 x 10^25 molecules of water
If 5.0 moles of propane react, how many molecules of water – There are 6.022×10^23 molecules in every mole . In 1 mole of water there are 6.022×10^23 molecules. Calculate the moles of water from the moles of propane. From the equation. 1 mole of C3H8 gives 4 moles of H2O. So 5.0 moles of C3H8 gives. 5.0 moles C3H8 x ( 4 moles H2O / 1 mole C3H8) = 20 moles H2OAnswer: molecules of water are produced ( assuming excess of oxygen). STEP BY STEP EXPLANATION : according to the given balanced equation , ⇒ we see that , 1 mole of ( propane ) reacts with 5 moles of (oxygen) to give 3 moles of ( carbon di oxide ). and 4 moles of (water) respectively.. 1 mole of reacts to give 4 moles of ∴ 5 moles of reacts to give ' ' moles of(a) The number of moles and the mass of Mg required to react with 5.00 g of HCl and produce MgCl 2 and H 2. (b) The number of moles and the mass of oxygen formed by the decomposition of 1.252 g of silver(I) oxide. (c) The number of moles and the mass of magnesium carbonate, MgCO 3, required to produce 283 g of carbon dioxide. (MgO is the other
