During an experiment, the scale you have been using is broken and you are to find the mass of a silver ring. You obtain the density of silver from a reference book and it is 10.5 g/mL. You then dropped the ring into a graduated cylinder and the water surface rises from 32.7 mL to 56.8 mL. What is the volume of the ring?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
