Does water have more hydrogen or oxygen in it?
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
What percent by mass of each chloroform molecule is composed of hydrogen?
Each chloroform molecule (CHCl3) is composed of 25% hydrogen by mass. This is because the molecular weight of hydrogen is 1, with one hydrogen atom in each chloroform molecule, and the molecular weight of chloroform is 119.38.
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
One mole of hydrogen molecules (H2) contains 2 hydrogen atoms per molecule, while one mole of hydrogen atoms contains single hydrogen atoms. Since the mass of a hydrogen atom is approximately half the mass of a hydrogen molecule, the molar mass of hydrogen molecules is higher than the molar mass of hydrogen atoms.
Who has greater kinetic energy a hydrogen atom or a carbon atom moving at the same speed?
The carbon atom would have greater kinetic energy compared to the hydrogen atom because kinetic energy is directly proportional to the mass of the object. Since the carbon atom is heavier than the hydrogen atom, it would possess more kinetic energy when moving at the same speed.
How many times a he atom is lighter than a haemoglobin molecules?
A hydrogen atom is about 1836 times lighter than a single hemoglobin molecule. This is because the atomic mass of a hydrogen atom is approximately 1 atomic mass unit (amu), while the molecular mass of a hemoglobin molecule is roughly 1836 amu.
Is the mass of a hydrogen atom 16 times greater than an oxygen atom?
No, it is inverse.
If the mass of water is 4.5 times greater than the mass of helium how does the mass of a water molecule compare with the mass of a helium atom?
The mass of the water molecules is greater than the mass of the helium atoms. It just so happens I had the same question in science, and that's what I put down. It might be wrong, it might not. But I'd be at least at like 65-35% chance it's right.
Why does a heavy water molecule have more mass than a normal water molecule?
Heavy water is formed from an isotope of Hydrogen called Deuterium which is 1 proton and 1 neutron whereas a normal hydrogen atom is only 1 proton. The extra particle causes the atom to have more mass and causes it's density to be greater than that of water

How can that the body has 10 percent hydrogen and 63 percent of the atoms are hydrogen?
Hydrogen is the lightest of all elements, having atoms that are only a fraction of the mass of all other elements. For example, an oxygen atom has about 16 times the mass of a hydrogen atom. So while a water molecule contains 2 hydrogen atoms and 1 oxygen atom (and water makes up most of the human body), the single oxygen atom accounts for most of the mass of the molecule.
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.
Mass of Hydrogen gas molecule?
The mass of a hydrogen gas molecule (H2) is approximately 2 atomic mass units (amu). This is because each hydrogen atom has a mass of roughly 1 amu, and a hydrogen gas molecule consists of two hydrogen atoms bonded together.
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
How many times a he atom is lighter than a haemoglobin molecules?
A hydrogen atom is about 1836 times lighter than a single hemoglobin molecule. This is because the atomic mass of a hydrogen atom is approximately 1 atomic mass unit (amu), while the molecular mass of a hemoglobin molecule is roughly 1836 amu.
