Answer: There will be 0.00002 meq per Liter of the solution.
Explanation:
Normality is defined as the umber of gram equivalents dissolved per liter of the solution.
[tex]Normality=\frac{\text{no of gram equivalents} \times 1000}{\text{Volume in ml}}[/tex]
[tex]Normality=\frac{\text{given mass}\times 1000}{\text {Equivalent mass}\times {\text{Volume in ml}}}[/tex]
Equivalent weight is calculated by dividing the molecular weight by n factor. [tex]{\text{Equivalent weight}}=\frac{\text{Molecular weight}}{n}[/tex]
n= charge for charged species , For [tex]Ca^{2+}[/tex] , n =2
[tex]{\text{Equivalent weight}}=\frac{40}{2}=20g[/tex]
[tex]\text{no of gram equivalents}=\frac{0.775g}{20g/mol}=0.04gramequivalents[/tex]
[tex]Normality=\frac{0.04\times 1000}{1925}=0.02eq/L=0.00002meq/L[/tex]
Thus there will be 0.00002 meq per Liter of the solution.
