What compound has the highest percent of hydrogen by mess Water or hydrogen proxide?
Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
Which compounds contains the greatest percent of oxygen by mass?
Compounds like hydrogen peroxide (H2O2) and sodium chlorate (NaClO3) contain large percentages of oxygen by mass due to their chemical compositions. For example, in hydrogen peroxide, each molecule contains two oxygen atoms, making up a significant portion of its molecular weight.
What is the percent composition of hydrogen in hydrogen peroxide?
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
How do you find the molar mass of H2O2?
Atomic weight of oxygen is 15,999. Atomic weight of hydrogen is 1,008. Two hydrogen atoms: 2,016. Two oxygen atoms: 31,998. The sum is the molar mass of hydrogen peroxide: 34,014.
The mass percent of hydrogen in hydrogen peroxide H2O2?
The mass percent of hydrogen in hydrogen peroxide (H2O2) is 5.88%. This is calculated by taking the total mass of hydrogen in one molecule of H2O2 (2.01 g) divided by the total molar mass of H2O2 (34.02 g/mol) and multiplying by 100.
What is oxygen to hydrogen mass ratio h2o2?
16

Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
What is the relative atomic mass of hydrogen peroxide?
The relative atomic mass of hydrogen peroxide, H2O2, is approximately 34.01 g/mol. This value is calculated by adding the atomic masses of the elements in the molecule (2 hydrogen atoms and 2 oxygen atoms).

What is the percent composition of hydrogen in hydrogen peroxide?
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
If the mass of one oxygen atom from water is 16amu what is the mass of one of the two oxygen atoms from hydrogen peroxide?
It's also 16 amu, ignoring the slight possibility of a different isotope.
How do you find the molar mass of H2O2?
Atomic weight of oxygen is 15,999. Atomic weight of hydrogen is 1,008. Two hydrogen atoms: 2,016. Two oxygen atoms: 31,998. The sum is the molar mass of hydrogen peroxide: 34,014.
What is the Mass in Grams of 1.50 moles of hydrogen peroxide?
The molar mass of hydrogen peroxide (H2O2) is 34.01 g/mol. To find the mass of 1.50 moles, you would multiply the number of moles by the molar mass: 1.50 moles * 34.01 g/mol = 51.015 grams. So, the mass of 1.50 moles of hydrogen peroxide is 51.015 grams.
The mass percent of hydrogen in hydrogen peroxide H2O2?
The mass percent of hydrogen in hydrogen peroxide (H2O2) is 5.88%. This is calculated by taking the total mass of hydrogen in one molecule of H2O2 (2.01 g) divided by the total molar mass of H2O2 (34.02 g/mol) and multiplying by 100.
How does the law of definite proportions explain the fact that although water and hydrogen peroxide consist of the same elements have different properties?
First find out what the law of definite proportions is. Then explain the fact that water and hydrogen peroxide consist of the same elements. Then find out if they have different or the same properties.
How many hydrogen peroxide molecules are expected if 100 oxygen molecules react with 10 hydrogen molecules?
Hydrogen Peroxide is expressed as H2O2, so you would assume that the molecular density would require you to only utilize 50 grams of hydrogen peroxide in order to get the required oxygen. However, Oxygen is a heavier atomic mass than Hydrogen, and therefore would require a slightly lower total of H2O2 in order to get the amount of oxygen required. by taking the atomic weight of both atoms, dividing the weights to find the percentage of the H2O2 that is Oxygen, you will be able to tell how much of the original substance you will need to divide in order to get the oxygen.
Which two elements make up three-fourths of the human body?
There is sixty percent water in your body. Water is made up of oxygen and hydrogen. There are double the number of hydrogen atoms or molecules as compared to oxygen in the water. But you have the mass of oxygen atom or molecule is 16 times more than that of hydrogen atom or the molecule. In case of water hydrogen to oxygen mass is one to eight, in proportion.
