Answer:
The answer is
<h2>219.5 mL</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 4500 g
density = 20.5 g/cm³
We have
We have the final answer as
<h3>219.51 mL</h3>Hope this helps you
Answer:
The answer to your question is d. 0.5 M
Explanation:
Data
[A] = 1M
K = 0.5
Concentration of B and C at equilibrium = x
Concentration of A at equilibrium = 1 - x
Equation of equilibrium
k =
Substitution
Simplification
0.5 =
Solve for x
0.5(1 - x) = x²
0.5 - 0.5x = x²
x² + 0.5x - 0.5 = 0
Find the roots x₁ = 0.5 x₂ = -1
There are no negative concentrations so the concentration of A at equilibrium is
[A] = 1 - 0.5
= 0.5 M
