what volume of 0.250mol/L solution could you make with 55.9g

what volume of 0.250mol/L solution could you make with 55.9g of potassium chloride KCl(s)Mercury compounds are poisonous but mercury ions can be removed from a solution by precipitating insoluble mercury(ii) sulfide HgS(s). Determine the minimum volume of 0.0783mol/L sodium sulfide Na2S(aq) that is needed to precipitate all the mercury ions in 75.5mL of 0.100mol/L Hg(NO3)2(aq)a 15.8g strip of zinc metal was placed in 100.0mL of silver nitrate AgNO3(aq). when the reaction was complete the strip of zinc had a mass of 13.1g. what was the concentration of the silver nitrate solutiondocument only even number 2 4 6 8 10 12calculate the molar concentration of iodide ions in each aqueous solutiona) 15g of potassium iodide dissolved in 200mL of solutionb) 12g of calcium iodide dissolved in 180mL of solution
