Given :
Volume , V = 500 mL .
Molarity , M = 0.5 M .
Molecular mass of NaCl is [tex]58.4\ g/mole[/tex] .
To Find :
How many grams of NaCl is required .
Solution :
Let , NaCl required is x gram .
Molarity is given by :
[tex]M=\dfrac{\text{Number of moles}}{\text{Volume (in liters) }}\\\\M=\dfrac{m}{M\times V}\\\\0.5=\dfrac{x}{58.4\times 0.5}\\\\x=0.5^2\times 58.4\ g\\\\x=14.6\ g[/tex]
Hence , this is the required solution.
