Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL

Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
