Answer:

( About ) 5.7 grams

Explanation:

[tex]Molarity = 0.135 mol L^{-1}[/tex]

Every [tex]1L = 10^3 ML[/tex]

.135 Moles of Agno3

[tex]250 ML = \frac{10^3ML}{4}[/tex]

[tex]\frac{0.135}{4} = (0.03375 Moles of Agno3)[/tex]

[tex]0.03375 m[/tex] · [tex]\frac{169.87g}{1 M}[/tex]

[tex]0.03375 m[/tex] · [tex]\frac{169.87g}{1 M} = 5.7331125[/tex]

[tex]Solution = About 5.7 Grams[/tex]

*169.87g = weight of silver Nitrate (Agno3)
