The volume : V₁ = 1.29 ml
<h3>Further explanation</h3>
Given
V₂=450 ml
M₂=0.02
M₁=7.0
Required
V₂
Solution
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
n₁=n₂
Dilution formula :
M₁V₁=M₂V₂
Input the value
V₁= (M₂V₂)/M₁
V₁ = (0.02 x 450)/7
V₁ = 1.29 ml

Explanation:
Answer:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.
Explanation:
<span>Get into moles first. .0590 grams over 540.8 grams per mole = 1.09 x l0^-4 moles
Sr3(As04)2 = 3 Sr++(aq) plus 2 As04^-3(aq)
Ksp = (Sr++)^3(As04^-3)^2
(Sr++) = 3 X l.09 x l0^-4 = 3.27 x l0^-4
(As04^-3) = 2 x l.09 x l0^-4 = 2.18 x l0^-4
<span>Ksp = (3.27 x l0^-4)^3 (2.18 x l0^-4)^2 which equals 1.66 x 10^-18th
