The solution to the problem is as follows:

The weight of solute required = Molarity x Molecular mass x Volume of solution in mL /1000 =0.15 x 170 x 175 / 1000 = 4.4625g 

Take 4.4625g of AgNO3 and disolve in certain quantity of water(<175 mL) and finally make up the solution to 175mL with water.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer: Therefore, we need to dissolve 4.5 g of [tx]AgNO_3[/tex] and make the volume upto 175 ml.

Explanation:

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

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n= moles of solute  

[tex]V_s[/tex] = volume of solution in ml = 175.0 ml

[tex]moles of solute =\frac{\text {given mass}}{\times {\text {molar mass}}=\frac{x}{170g/mol}[/tex]

Now put all the given values in the formula of molarity, we get

[tex]0.150M=\frac{x\times 1000}{170\times 175.0ml}[/tex]

[tex]x=4.5g[/tex]

Therefore, we need to dissolve 4.5 g of [tx]AgNO_3[/tex] and make the volume upto 175 ml.
