Respuesta :

Molarity = moles of solute / liter of solution

in your case ,

1) liter of solution is = 18 L

2) mole of solute(NaCl) = gram/molar mass = 64/58.44= 1.095

Now you can put both values from 1 and 2 in the first equation to calculate the Molarity

Answer: 0.06 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

[tex]Molarity=\frac{n}{V_s}[/tex]

where,

n= moles of solute  [tex]NaCl[/tex]

[tex]Moles=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{64g}{58.5g/mol}=1.09moles[/tex]  

[tex]V_s[/tex] = volume of solution  in Liters = 18 L

Putting in all the values we get,

[tex]Molarity=\frac{1.09moles}{18L}=0.06M[/tex]

Thus the molarity of solution is 0.06 M
