the balanced equation for the combustion of ethane is as follows
2C₂H₆ + 7O₂ --> 4CO₂ + 6H₂O
molar ratio of C₂H₆ to H₂O is 2:6
this means that when 2 mol of C₂H₆ react 6 mol of H₂O are produced
for every 1 mol of C₂H₆ that reacts thrice the number of moles of H₂O are produced
therefore when 1.4 mol of C₂H₆ reacts - 3 x 1.4 = 4.2 mol of H₂O are produced
the answer is 4.2 mol
Answer: 41.46 L
Explanation:
La ecuación que describe relación entre presión, volumen, temperatura y la cantidad (en moles)
de un gas ideal es:
PV = nRT
Donde: P = Presión absoluta
, V= Volumen , n = Moles de gas
, R = Constante universal de los gases ideales, T = Temperatura absoluta,
R = 0.082 L. atm/mol. °K
V = nRT/P
Calculanting n
n = mass/ molecular mass
<h3>n = 4 g / 2g. mol⁻¹</h3><h3>n = 2 mol</h3><h3>T =25⁰ + 273 ⁰K = 298 ⁰K</h3><h3>V = (2 mol ₓ0.082 L. atm / mol.°K x 298 ⁰K) / 1.18 atm = 41.46 L</h3>
