Answer:

Moles of potassium chloride = 0.000672 moles

Explanation:

Considering:

[tex]Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}[/tex]

Or,

[tex]Moles =Molarity \times {Volume\ of\ the\ solution}[/tex]

Given :

For potassium chloride :

Molarity = 0.12 M

Volume = 5.6 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 5.6×10⁻³ L

Thus, moles of potassium chloride  :

[tex]Moles=0.12 \times {5.6\times 10^{-3}}\ moles[/tex]

Moles of potassium chloride = 0.000672 moles
