what is the mass/volume % concentration of 2.75g of k2SO4 dissolved in 550.0 mL of solution
Concentration is the amount of solute dissolved in a certain amount of solution: concentration of a solution=amount of soluteamount of solution Solution concentrations are usually given as one of the following: Mass percent (m/m)—the mass of the solute in grams for exactly 100 g of solution Volume percent (v/v)—the volume of solute in exactly 100 mL of solution Mass/volume percent (m/v)—the mass of solute in grams for exactly 100 mL of solution Molarity (M)—the number of moles of solute in...
The mass of magnesium hydroxide that is dissolved in 125 mL of a saturated solution is grams. The mass of lead carbonate that is dissolved in 150 mL of a saturated solution is grams. The volume of water needed to dissolve 0.0606 grams of calcium chromate is L. Assume no volume change upon addition of the solid.

A volume of 70.0 mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H2SO4). What was the molarity of the KOH solution if 15.2 mL of 1.50 M H2SO4 was needed? The equation is 2KOH(aq)+H2SO4(aq)?K2SO4(aq)+2H2O(l) part b: Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2O2, can be titrated against a solution of potassium permanganate, KMnO4. The following equation represents...
