Explain how you would prepare 60 cm³ of an aqueous solution of AgNO3 of strength 0.030g AgNO3 per cubic centimeter?

And so you want a concentration with respect to #AgNO_3# of #0.030*g*cm^-3#?

Explanation:

Well, we take the product....#0.030*g*cm^-3xx60*cm^3=1.80*g#..

And so we add a mass of #1.80*g# of silver nitrate to a #60*cm^3# volume of water. (The volume change upon dissolution would be quite negligible).

And this represents a molar concentration of...

#[AgNO_3]=((1.80*g)/(169.87*g*mol^-1))/(60*cm^3xx10^-3*L*cm^-3)=0.177*mol*L^-1#...

Nitrates are generally soluble in aqueous phase, which is why we use this salt to get the silver ion up into aqueous solution....
