The answer for the following problem is mentioned below.
- <u><em>Therefore the final moles of the gas is 14.2 × </em></u>
<u><em> moles.</em></u>
Explanation:
Given:
Initial volume (
) = 230 ml
Final volume (
) = 860 ml
Initial moles (
) = 3.8 × moles
To find:
Final moles (
)
We know;
According to the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of the moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
So;
V ∝ n
= 
where,
() represents the initial volume of the gas
() represents the final volume of the gas
() represents the initial moles of the gas
() represents the final moles of the gas
Substituting the above values;
= 
= 14.2 × moles
<u><em>Therefore the final moles of the gas is 14.2 × </em></u><u><em> moles.</em></u>
Answer:
<h3>Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.</h3>
The volume of the sample after the reaction : V₂=5.484 L
<h3>Further explanation</h3>
Given
Reaction
2HBr(g) + Cl2(g) => 2HCl (g)+Br2(g)
0.1100 mol of HBr(g)
5x10⁻² mol of Cl2(g)
Required
The volume of the sample after reaction
Solution
Find limiting reactant :
0.11/2 : 0.05/1 = 0.055 : 0.05
Limiting reactant : Cl₂
mol Products based on mol Cl₂
mol products = mol HCl + mol Br₂
mol products = 2/1x0.05 + 1/1x0.05
mol products = 3 x 0.05 = 0.15
mol reactants = 0.11 + 0.05 = 0.16
<em>From Avogadro's law, </em>
In the same T, P, and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
1 = reactants, 2 = products
Input the value :
5.85/0.16=V₂/0.15
V₂=5.484 L
