25.0 g of glucose were dissolved in water and diluted to provide the total solution volume of 100.0 mL. A dose of 2000. milligrams had to be administered. What volume of the solution is necessary to deliver the required dose?

Copper(II) oxide CuO reacts with hydrochloric acid HCl to produce copper(II) chloride CuCl2 and water. How many moles of CuCl2 were produced if 160 g of CuO was used in this process?

A volume of 40.0 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 24.7 mL of 1.50 M H2SO4 was needed? The equation is

An aqueous solution of potassium hydroxide is standardized by titration with a 0.168 M solution of perchloric acid. If 18.9 mL of base are required to neutralize 10.5 mL of the acid, what is the molarity of the potassium hydroxide solution?

The aqueous solution with volume of 300. mL contains 10.5 g of potassium hydroxide KOH. What is the molarity cM of this solution?
