Answer:
4.95L
Explanation:
Using Charle's law equation;
V1/T1 = V2/T2
Where;
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the question, the following information was given:
V1 = 4.50L
V2 = ?
T1 = 27°C = 27 + 273 = 300K
T2 = 57°C = 57 + 273 = 330K
Using V1/T1 = V2/T2
4.50/300 = V2/330
Cross multiply
300 × V2 = 4.5 × 330
300V2 = 1485
V2 = 1485 ÷ 300
V2 = 4.95L
From the reaction, the volume of the oxygen required is 89.6 L.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with the process by which the mass of reactants or products in a reaction is obtained from the balanced reaction equation.
In this case, the balanced reaction is equation is;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Number of moles of CO2 = 88.0 g/44 g/mol = 2 moles
2 moles of O2 produced 1 mole of CO2
x moles of O2 produces 2 moles of CO2
X = 4 moles
1 mole of oxygen occupies 22.4 L hence 4 moles of oxygen occupies 4 * 22.4 L = 89.6 L
