What is the density of an object that raises the level of water in a graduated cylinder from 13.5mL. to 17.4mL. and has a mass of 32.5g. How many grams of lead (IV) sulfate are in 225.0mL of a 0.6554 M solution? What is the theoretical yield of iron oxide when 55.65g of iron(11) nitrate reacts with 12.75g of aluminum oxide? A 25.0 mL volume of 2.65 M sulfuric acid is titrated with potassium hydroxide. At the equivalence point, 65.7mL of base were added. How many moles of acid were neutralized? In a titration of unknown triprotic acid, 63.5 ml. of 0.556 M calcium hydroxide are needed to neutralize 25.0 mL of the acid. What is the molarity of the triprotic acid? A 50.0 mL sample of a monotonic acid solution was neutralized with 36.7 mL of a 2.25M sodium hydroxide solution. If the acid solution was made by adding 5.65g of acid to enough water to make 50.0mL, what is the molecular weight of the acid? How many mL of a 12.0 M stock solution are needed to make 500.0mL of a 0.100 M solution? A student reacts 16. 75g of magnesium acetate with excess barium hydroxide to yield 2.46 g of magnesium hydroxide. What is the percent yield? What is the volume of a block of salt weighing 53.5g with a density of 2.16 g/cm^3?
