No. of moles * molar mass of Cu2CrO4
2.55*335
Answer:
relative rate of diffusion is 1.05
Explanation:
According to Graham's law of difussion:
Rate of diffusion is inversely proportional to the square root of molecular weight of a molecule.
For two given molecules:
The given molecules are
Water = 18.01
Heavy water =20.03
Thus the relative rate of diffusion will be:
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
Answer:
to my own understanding I think it's 65 percent
