Answer b) a to c would be considered one wavelength.
The molarity of the solution will be 3.45 M
<h3>Further explanation
</h3>
Dilution is the process of adding a solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
Can be formulated :
M₁V₁=M₂V₂
M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = Molarity volume of the solution after dilution
The initial solution
345 mL of a 2.5 M NaCl solution.
M₁=2.5 M
V₁=345 ml
The solution after boiled :
V₂=250 ml

KE @ 0.5m = 0.5mv^2 = 2.91 J
ME @ 0.5m = 4.41 + 2.91 = 7.32 J
7.32 J</span>
Answer:
Leukonychia is a condition where white lines or dots appear on your finger or toenails. This is a very common issue and entirely harmless. Many healthy adults have these spots at some point in their lives, so developing them is likely not a sign of a serious medical condition.
