Draw the diazonium cation formed when cytosine reacts with NaNO2 in the presence of HCl. cytosine reacts with N a N O 2 and H C l. Cytosine is a 6 membered ring consisting of a nitrogen bonded to a hydrogen at position 1, a carbon double bonded to oxygen at position 2, and a nitrogen at position 3 that is double bonded to the carbon on position 4. There are carbons at positions 5 and 6 and they are double bonded to each other. Lastly, the carbon in position 4 has an N H 2 substituent.

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.
