649 mg of a pure diprotic acid (this means that the acid is capable of donating two hydrogen ions or protons) was titrated with 12.32 mL of a 0.684 M potassium hydroxide solution. What is the molar mass of the acid? The balanced equation is: K2X + 2 HOH H2X 2 KOH 2. The molarity of sulphuric acid in a fully charged car battery is 5.2 M. When fully discharged the molarity is 4.8 M. A 2.00 mL sample of battery acid was titrated with 31.26 mL of a 0.621 M sodium hydroxide solution. Does the battery need to be recharged? In the vernacular, what is the molarity of the battery acid? Document your answer. 3. A student titrated 38.00 mL of a 0.522 M sodium hydroxide solution with 25.00 mL of a 0.785 M hydrochloric acid solution. Which is the limiting reagent? How many mL of excess reactant will remain? 175

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
