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.
The molecular formula for hydrogen sulfide is H2S. What does the formula indicate about the composition of a 1.0 gram sample of hydrogen sulfide?
All of the molecules are identical combinations of two hydrogen atoms and one sulfur atom.
How many molecules of hydrogen are in 2.44 moles of hydrogen?
There are 1.471 x 10^24 molecules of hydrogen in 2.44 moles of hydrogen. This is calculated by using Avogadro's number, which is 6.022 x 10^23 molecules per mole.
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
How many molecules are present in the C3H4 sample?
There are Avogadro's number of molecules present in one mole of any substance. For C3H4, the molecules in one mole would be equal to Avogadro's number multiplied by 3 (for 3 carbon atoms) plus 4 (for 4 hydrogen atoms), which equals 3 * 6.022 x 10^23 + 4 * 6.022 x 10^23 = 26.056 x 10^23 molecules.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many molecules are in one-thousandth of a mole of H2?
There are 6.022 x 1023 molecules of hydrogen in 1 mole of H2so there are 6.022 x 1020 molecules in 1/1000 ( one thousandth) of a mole.
How many moles in a sample of 6.022x1023 molecules of colbalt chloride?
6.022*10^23 molecules of anything is one mole of that thing
Why one mole of hydrogen molecules and one mole of hydrogen atoms have different masses?
Because each hydrogen molecule contains 2 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.

How many atoms of hydrogen are in 2NH3?
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.

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 moles of hydrogen will be produced if 0.36 moles of zinc react with an equal amount of H2SO4?
Zn + H2SO4 ---> ZnSO 4 + H2 so one mole of zinc and 1 mole of sulfuric acid produces one mole of hydrogen molecules and thus two moles of hydrogen atoms. So 0.36 moles of zinc will produce 0.36 moles of hydrogen molecules and thus 0.72 moles of hydrogen atoms.
