What is the solubility of silver nitrate if only 11.1 g can dissolve in 5.0 g water at 20°C?
A compound's solubility in water is usually expressed in grams per
In your case, you can use the information given to you to find the solubility of silver nitrate,
So, you know that you can dissolve
#100color(red)(cancel(color(black)("g H"_2"O"))) * "11.1 g AgNO"_3/(5.0color(red)(cancel(color(black)("g H"_2"O")))) = "222 g"#
This means that the solubility of the salt will be
#"solubility AgNO"_3 = color(green)(|bar(ul(color(white)(a/a)color(black)("220 g/100 g H"_2"O")color(white)(a/a)|)))#
The answer is rounded to two sig figs, the number of sig figs you have for the mass of water that can dissolve
