how many moles are there in 56.0 grams of silver nitrate?
Of which concentration do you enquire?
From the definition of molar concentration, the required amount of solute for the solution specified is 0.125 moles. The gram formula mass for potassium benzoate trihydrate is 214.26. Therefore, the mass required is 0.125 X 214.26 or about 26.8 grams, to the justified number of significant digits.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
Ag+ = 50 x 0.05 = 2.5 millimoles CrO4^2- = 100 x 0.06 = 6 millimoles Ag2CrO4 moles = 1.25 x 10^-3 moles formed.

This solution contain a specified concentration of sodium chloride.
Of which concentration do you enquire?
This solution contain a specified concentration of sodium chloride.
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
Identification of silver is done as follows: dissolve a little amount in nitric acid. Add to that solution potassium chromate solution. If silver present the orange will become red

The specified amounts of materials add to 814.78 grams total. Therefore, the percentage concentration by mass of potassium iodate is 100(3.05/814.78) or 0.374 percent, to the justified number of significant digits, and the percentage concentration by mass of potassium hydroxide is 100(6.23/814.78) or 0.765 percent, to the justified number of significant digits.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.

That will vary with both the compound and its concentration in the solution (neither of which were specified in the question).
