A sample of hydrogen gas (3.2 l) at 3.5 atm and 25 °c was combined with 5.2 l of nitrogen gas at 7.3 atm and 25 °C at constant temperature in a 15.0 l flask. Assuming the initial pressure in the flask was 0.00 atm and the temperature upon mixing was 25 °., What is the total pressure (atm) in the flask?

What is the number of atoms in 3.54 mol s

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.
