A chemist prepares a solution of copper(II) fluoride (CuF2) by measuring out 0.032 µmol of copper(II) fluoride into a 500 mL vol
schepotkina [342]

Answer : The concentration of copper(II) fluoride in the solution is, 6.4\times 10^{-8}mole/L

Explanation : Given,

Moles of copper(II) fluoride = 0.032 μ

mol = 0.032\times 10^{-6}mol=3.2\times 10^{-8}mol

conversion used : \mu mol=10^{-6}mol

Volume of solution = 500 mL

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Moles of copper(II) fluoride}\times 1000}{\text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

\text{Molarity}=\frac{3.2\times 10^{-8}mol\times 1000}{500mL}=6.4\times 10^{-8}mole/L

Therefore, the concentration of copper(II) fluoride in the solution is, 6.4\times 10^{-8}mole/L
