Calculate the mass/volume percent when 55.1 grams of KOH is dissolved in 450 mL of water (d = 1.00 g/mL) to give a solution with a density of 1.02 g/mL. A solution is prepared by dissolving 11.0 g of KOH in enough water to make 80.0 mL of solut...
Suppose that I have dissolved 1mol of KOH and 1 mol of NaCl into water. So there have to be 1 mol of K+, 1 mol of Na+, and so on to Cl-, OH-. If someone asks me : "What substances are in the solution ?", is that wrong if I answer "NaOH and KCl", or I must say ...
A dilution equation allows us to determine the concentration of a solution after adding the solvent or solute to the solution. Suppose we add solvent to an existing solution; the solute concentration is decreased, and it can be evaluated using the ...
A solution has 140 grams of KOH dissolved in 5 L of water. What is the pH? What is the pH of a solution prepared by mixing 50.0 mL of 0.010 mol/L HCl(aq) and 50.0 mL of 0.010 Ca(OH)2(aq)? Assume the temperature is 25 degrees Celsius...
If 1.12 grams of KOH is dissolved to make 250 mL of solution, what is the concentration (in M) of KOH?What is the final volume of a 1% KOH solution prepared from a 10ml of a 20% KOH solution?You are given 500 mL of a standardized 1.0 M KOH solution. What volume of ...
