What if a 50.0 mL o a 0.500 M solution of H2O2 is decomposed what mass of O2 will be produced?
The chemical equation for the decomposition of H2O2 is 2 H2O2 -> 2 H2O + O2. This shows that two moles of H2O2 are required to produce each mole of O2. By definition, a 0.500 M solution of H2O2 contains 0.500 moles of H2O2 in each liter of solution. Solutions are always homogeneous; therefore, 50,0 mL of such a solution will contain (0.500)(50.0/1000) or 0.0250 moles of H2O2. As noted in the first paragraph, this will produce half as many, or 0.0125, moles of O2. The gram molar mass of O2 is twice the gram atomic mass of oxygen, or 31.9988. Therefore, decomposition of this amount of H2O2 will produce 31.9988 X 0.0125 or 0.400 gram of O2, to the justified number of significant digits.
A certain amount of hydrogen peroxide was dissolved in 100 ml of water and then titrated with 1.68m kmno4 how much h2o2 was dissolved if the titration required 22.3 ml of the kmno4 solution?
To calculate the amount of hydrogen peroxide (H2O2) dissolved, you can use the equation: moles of KMnO4 = moles of H2O2. Firstly, calculate the moles of KMnO4 (given concentration and volume). Then, use the balanced chemical equation to determine the moles of H2O2, as they have a 1:1 stoichiometric ratio. Finally, convert moles of H2O2 to grams using the molar mass to find the amount dissolved in the solution.
How do I calculate mass of H2O2 solution?
To calculate the mass of a hydrogen peroxide (H2O2) solution, you need to know the volume of the solution and its concentration (usually given in % or M). Use the formula: mass = volume x (concentration/100) x density of H2O2 solution. The density of the solution can vary based on its concentration, so check a reference source for the specific density value.

What is basic health assessment?
Health Assessment is the observation of the systems of the body. The assessment is typically preformed to check for abnormalities or to set a baseline for existing abnormalities in order to monitor for changes from that baseline to determine if a condition is improving or getting worse.
