A 72.4 mL solution of Cu(OH) is neutralized by 47.8 mL of a 0.56 M H2(C204) solution. What is the concentration of the Cu(OH)?​

Respuesta :

Answer: The concentration of [tex]Cu(OH)_{2}[/tex] is  0.369 M.

Explanation:

Given: [tex]V_{1}[/tex] = 72.4 mL,     [tex]M_{1}[/tex] = ?

[tex]V_{2}[/tex] = 47.8 mL,       [tex]M_{2}[/tex] = 0.56 M

Formula used to calculate the concentration of [tex]Cu(OH)_{2}[/tex] is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\M_{1} \times 72.4 mL = 0.56 M \times 47.8 mL\\M_{1} = \frac{0.56 M \times 47.8 mL}{72.4 mL}\\= 0.369 M[/tex]

Thus, we can conclude that the concentration of [tex]Cu(OH)_{2}[/tex] is  0.369 M.
