What is the concentration of a .100 L aqueous solution that contains .014mol of KCL

0.14 M

Explanation:

Given that,

Amount of moles of KCl (n) = 0.014

Volume of aqeous solution (v) = 0.100 L

Concentration of KCl solution (c) = ?

Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence

c = n / v

c = 0.014 moles / 0.100 L

c = 0.14 M (note that 0.14 M is same as concentration in mole per litres which is molarity)

Thus, the concentration of a .100 L aqueous solution that contains .014mol of KCL is 0.14 M
