If 5.0 moles of C3H8 react, how many molecules of water are formed?

artcher [175]

Balance Chemical Equation for combustion of Propane is as follow,

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

According to equation,

1 mole of C₃H₈ on combustion gives = 4 moles of H₂O
So,
5 moles of C₃H₈ on combustion will give = X moles of H₂O

Solving for X,
X = (5 mol × 4 mol) ÷ 1 mole

X = 20 moles of H₂O

Calculating number of molecules for 20 moles of H₂O,
As,
1 mole of H₂O contains = 6.022 × 10²³ molecules
So,
20 moles of H₂O will contain = X molecules

Solving for X,
X = (20 mole × 6.022 × 10²³ molecules) ÷ 1 mol

X = 1.20 ×10²⁵ Molecules of H₂O

P4O10 -> 4P+5O2 How many moles of phosphorus would be produced if 5.3 mol of P4O10 reacted?

viktelen [127]

Answer:

21.2 moles.

Explanation:

Hello!

In this case, for the given chemical reaction, we can see there is a 1:4 mole ratio between tetraphosphorous decaoxide and phosphorous; therefore, the following proportional factor provides the requested moles of phodphorous:

$n_P=5.3molP_4O_{10} *\frac{4molP}{1molP_4O_{10}} \\\\n_P=21.2molP$

Best regards!
