To determine the percentage of oxygen in FeCr2O4, you would first calculate the molar mass of the compound (iron(II) chromite) using the atomic masses of each element (Fe = 55.85 g/mol, Cr = 51.996 g/mol, O = 16 g/mol). Then, calculate the molar mass percentages of each element within the compound, and finally, determine the percentage of oxygen by mass in the compound.

If 230 g sample of a compound contains 136.6 g of carbon 26.4 g of hydrogen and 31.8 g of nitrogen The rest is oxygen What is the mass percent of oxygen in the compound?

The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O

How find percent compsotion of oxygen in Na2O?

To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.

What is the difference between atomic percent and weight percent?

Atomic percent is based on the number of atoms in a sample. So if the sample has x number of oxygen atoms and x number of iron atoms it would report 50% oxygen and 50% iron (atomic percent). Weight percent is based on the mass of the elements detected. So if we used the above example and reported the results as weight percent we would get 22.3% oxygen and 77.7% iron. Weight percent takes into consideration the mass or atomic weight of the elements and not just the number of atoms. Most people use weight percent although for chemistry atomic percent may be more useful.

Calculating Mercury in Mercury oxide by gravimetric analysis?

First take the mercury oxide and heat it so that it decomposes completely. This will drive off the oxygen gas and leave you with elemental mercury. Record the exact mass of the mercury that you have left at the end of the reaction. Divide this mass of mercury by the original mass of your mercury oxide sample and multiply by 100. This will be the percent mercury by mass in your original sample.


Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?

Oxygen atoms weigh more than Hydrogen atoms.
