At a certain temperature, the solubility of N2 N 2 gas in water at 2.38 atm a t m is 56.0 mg of N2 gas/100 g water m g o f N 2 g a s / 100 g w a t e r . Calculate the solubility of N2 N 2 gas in water, at the same temperature, if the partial pressure of N2 N 2 gas over the solution is increased from 2.38 atm a t m to 5.00 atm a t m .

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.
