Answer:

[KCl] = 1.33 M

Explanation:

Molarity is mol /L

Mol of solute in 1 L of solution

Volume of solution is 750 mL

750 mL / 1000 = 0.750 L

1 mol / 0.750L = M → 1.33

Answer:

[tex]M=1.3M[/tex]

Explanation:

Hello,

In this case, the molarity, which is a unit of concentration of liquid dissolutions, is defined as shown below:

[tex]M=\frac{n_{solute}}{V_{solvent}}[/tex]

Whereas the volume of the solvent must be in liters, therefore, the 750-mL solution is also equivalent to 0.750-L solution, hence, the molarity turns out:

[tex]M=\frac{1.0mol}{0.750L}\\M=1.3M[/tex]

Whereas the molar units (M) account for mole over L (mol/L).

Best regards.
