How many moles of each atom are in CHCl3?
The formula of trichloromethane is CHCl3. The usual molar formulas of the three elements are C, H2, and Cl2. Based on these formulas, one mole of trichloromethane contains one mole of carbon, one-half mole of hydrogen, and one and one-half moles of chlorine.
The lighter the atom the less mass in one mole of that atom?
Yes, that is correct. The molar mass of an element is directly proportional to its atomic weight. Lighter atoms have lower atomic weights, which means that one mole of a lighter atom will have less mass compared to one mole of a heavier atom.
How many atoms are in hydrogen and chlorine?
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
How many product atoms are there in hydrogen?
There is one atom of hydrogen in a hydrogen molecule.
How many hydrogen atoms are in Na2HPO4?
There are 2 hydrogen atoms in each formula unit of Na2HPO4.
Why one mole of hydrogen and one mole of H-atom have different masses?
The hydrogen molecule is diatomic, H2.
Is H an atom in chemistry?
H is the chemical symbol for Hydrogen and represents one hydrogen atom everywhere other than in a chemical equation where it represents one mole of hydrogen atoms.
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.
What is the mass of one hydrogen deuterium atom in grams?
Approximately 2 / (6.022 x 1023) = 3.32 x 10-24 grams
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
How many moles of each atom are in CHCl3?
The formula of trichloromethane is CHCl3. The usual molar formulas of the three elements are C, H2, and Cl2. Based on these formulas, one mole of trichloromethane contains one mole of carbon, one-half mole of hydrogen, and one and one-half moles of chlorine.
How many electrons are present in one mole of H2?
In one mole of H2, there are six electrons present. Two electrons are contributed by each hydrogen atom.
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many hydrogen atoms are present in 1 mole of acetic acid or CH3COOH?
CH3COOH CH3COO- + H+So there is only one acidic H atom.[Only the 'bold' H atom is acidic, the 3 'methyl' H's are not!]
Why one mole of hydrogen molecules and one mole of hydrogen atoms have different masses?
Because each hydrogen molecule contains 2 hydrogen atoms!
The lighter the atom the less mass in one mole of that atom?
Yes, that is correct. The molar mass of an element is directly proportional to its atomic weight. Lighter atoms have lower atomic weights, which means that one mole of a lighter atom will have less mass compared to one mole of a heavier atom.
How much combustion energy is released from two Hydrogen Atoms and one Oxygen Atom?
The combustion of two hydrogen atoms and one oxygen atom forming water releases approximately 483.6 kJ of energy.
