The solubility product constant for a certain metal phosphate, M3(PO4)2 is Ksp = 2.1 × 10−27. Its molar mass is ℳ = 279.04 g/mol. What is its solubility in g/L? Report your answer to TWO significant figures. Enter your answer in scientific notation using the appropriate boxes. Remember, a number like 1.6, in scientific notation is 1.6 × 100.

A titration is a procedure for determining the concentration of a solution by allowing it to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation- reduction reactions are used in titrations. For example, to find the concentration of an HCl solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCI from a calibrated tube called a buret. An indicator is also present and it will change color when all the acid has reacted. Using the concentration of the standard solution and the volume dispensed, we can calculate molarity of the HCl solution. A volume of 90.0 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 13.2 mL of 1.50 M H₂SO4 was needed? The equation is 2KOH(aq) + H₂SO4 (aq)→K₂SO4 (aq) + 2H₂O(1) Express your answer with the appropriate units. ► View Available Hint(s) molarity = Submit…

In a terrible accident, a solution consisting of 2.37 kg of nitric acid, HNO3, was spilled on the lab floor. Very quickly, you decide to throw 2.00 kg of sodium carbonate, Na2CO3, on the spilled acid. You then run out of the building due to the significant quantities of carbon dioxide that would form due to the reaction. As you stand outside, you wonder, "Did I add enough sodium carbonate to neutralize the acid?". a) Did you add enough sodium carbonate to neutralize the acid? Yes Ο No b) In the event that you did not add enough sodium carbonate, how much extra would be needed to completely neutralize the acid? If you have added enough, please enter a value of 0 (zero). Needed 0 c) In the event that you did add enough sodium carbonate, how much extra did you add? If you didn't add any extra, please enter a value of 0 (zero). Excess 09 g g

Will the calculated Molarity of NaOH be too high or too low or unaffected if the following happen: When you answer the question, consider how the situation affects the calculation of molarity of NaOH and moles NaOH, which is calculated from the mass of KHP. For each answer, you must supply a clear explanation for your answer. Often times, students will restate the facts rather than explaining why they chose the answer they chose. a) You add the weighed KHP to a flask containing a 60mL of water rather than 50 mL of water. Explain. Your answer must contain a well-thought-out and clearly written explanation. b) The buret is still wet with water on the inside when you add your NaOH solution. Explain c) The KHP is wet when you weigh it. Explain. d) You titrate past the equivalence point by 0.50mL Answer a-d
