Answer 2

Molarity of the solution = 0.08 M

Further explanation

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

`\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}`

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

0.5 lb=226,796 g

MW silver nitrat - AgNO₃ = 169,87 g/mol

mol AgNO₃ :

`\tt mol=(mass)/(MW)=(226.796)/(169.87)=1.335`

Molarity :

`\tt M=(1.335)/(16.75)=0.08`
