Answer:
The molarity will be "0.26 M".
Explanation:
The given values are:
Mass,
= 2.00 g
Volume of solution,
= 100 mL
or,
= [tex]\frac{100}{1000}[/tex]
= [tex]0.1 \ L[/tex]
Molar mass of KCl,
= 74.5 gm
Now,
Moles of KCl will be:
= [tex]\frac{Given \ mass}{Molar \ mass}[/tex]
= [tex]\frac{2}{74.5}[/tex]
= [tex]0.026[/tex]
hence,
The molarity will be:
= [tex]\frac{Moles \ of \ solute}{Volume \ of \ solution}[/tex]
On substituting the values, we get
= [tex]\frac{0.026}{0.1}[/tex]
= [tex]0.26 \ M[/tex]
