How do I calculate mass of H2O2 solution?
Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
Is the mass of a hydrogen atom different from the mass of an oxygen atom?
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
What is the percentage of hydrogen in hydrogen Bromide?
It all depends on what you're looking for. If you mean ratio of atoms, It is a one:one ratio, so 50% each If you mean mass, 1.0125% of the mass of one molecule is hydrogen and the other 98.9875% is bromine.
What is an example of the law of constant composition?
A compound always contains the same elements in the same proportions by mass. This is a formal way of saying that a compound always has the same formula, no matter how it is made or where it is found.
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?
Mass of H2O2 = 0.637 g
How do I calculate mass of H2O2 solution?
Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
What is the ratio of hydrogen to oxygen in H2O?
The atomic ratio is 2:1 The mass ratio is 1:8 because oxygen has an atomic mass 16 times greater than hydrogen
Which compound has a higher percent by mass of hydrogen- h2o or h2o2?
lets see. H20 you have 2.016 grams of hydrogen here to 16.0 grams oxygen 2.016/16.0 X 100 = 12.6% hydrogen by mass H2O2 you have the same 2.016 grams hydrogen here, but you have 32.0 grams oxygen in this molecule 2.016/32.0 X 100 = 6.3% so H2O has the higher percent by mass of hydrogen
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.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
h2o2
How percentage of oxygen is more in water than hydrogen?
This is true for mass-%. Oxygen is 16 times heavier than hydrogen, that outfigures the double elemental ratio for hydrogen to oxygen (2:1) by factor 8 times.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 g per mole. What is the molecular formula of this compound?
There is most likely a mistake in this question, as the mole ratio of O to H here is 0.94/0.059 = 16 : 1 which is not likely in nature, and it would also not have a molar mass of 34.0 g/mol. The answer is H2O2 (hydrogen peroxide) which has a molar mass of 34 g/mole, but the mole ratio of O to H is 1:1.
What is the difference between mass and water?
Mass is a unit of measurement and water is a substance. Namely a combination of hydrogen and oxygen in a 2 to 1 ratio.
What is evidence that supports the law of constant composition?
The mass ratio of carbon to oxygen in carbon dioxide is always 3:8 In a molecule of water, the mass of oxygen is always 8 times the mass of hydrogen
What is the ratio of oxygen atoms to hydrogen atoms in a water molecule?
2 hydrogen, 1 oxygen. The equation for water is H2O, meaning 2 parts hydrogen and 1 oxygen. Oxygen is a bigger element than hydrogen, hydrogen being the least dense substance on earth (which is why it rises in air) External links to a picture of a magnified water molecule:
What is the mass ratio from a hydrogen atom to ununoctium atom?
Mass of hydrogen atom = 1 amu Mass of ununoctium atom = 294 amu So ratio = 1 : 294
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
