how to calculate percent composition of oxygen?
608388
Determine the percent composition of the compound. Identify the "given" information and what the problem is asking you to "find." Subtract to find the mass of oxygen in the compound. Divide each element's mass by the mass of the compound to find the percent by mass.

We divide that by the total mass of the compound, multiply it by 100%, and get the mass percent of oxygen in hydrogen peroxide being about 94%.
240547
The percent composition of hydrogen peroxide is 94.07 percent oxygen and 5.93 percent hydrogen.
1175507
So the percentage of oxygen in sulphur dioxide is (32/64)*100=50%.

It is important to note that we can calculate the mass percentage composition by dividing the mass of a component by the total mass of the mixture. This ratio is then to be multiplied by 100. We also call it the mass percent(w/w) %.

To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. Then, you take the molar mass of just the element and divide it by the molar mass of the whole compound, and multiply by 100%.

Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.

Converting from Parts Per Million (ppm) to Percent (%) In order to express the results as a percent, divide the nutrient content (which is expressed in ppm) by 10,000. For example, if the reported value for P2O5 is 2,690 ppm, the calculation to convert to percent would be: 2,690 ppm ÷ 10,000 = 0.269%.

per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
