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, $6.4\times 10^{-8}mole/L$

Why are alloys preferable at times?

andriy [413]

Alloys are preferable at times because they offer interesting properties than pure metal. Alloys are made in order to modify or enhance properties, especially mechanical properties. Examples are stainless steel, brass and wrought iron.
