In some species of plants, mutations can cause a plant to have different patterns on their leaves, such as gold edges or white stripes. Plants with different patterns grow to the same size and produce offspring with similar patterns. However, these plants can have high mutation rates. As a result, a group of related plants can exhibit many patterns.

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.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
