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.
