Does 0.25 mole of o2 contain the same number of molecules as 0.25 mole of nh3?

yes, 1 mole is 6.02214179*10^23 molecules.
And both only have 1 atom,
so both have 1/4th this ammount of molecules and atoms.

∙ 10y ago0.25 mole of both the gases contain same amount of molecules. However, the number is atoms in NH3 is more than the number of atoms in O2.

What weighs more hydrogen atoms or carbon atoms?
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
How many molecules in one mole of ammonia?
6.022 x 1023 molecules. One mole of any substance has the same i.e. 6.022 x 1023 of its constituents particles.
Molecules of oxygen in a mole?
The number of any item in a mole is equal to Avogadro's number, or 6.0221415 × 10^23 items. So, in the case of O2, it would be 6.0221415 × 10^23 O2 molecules. It's like asking how many eggs in a dozen versus how many marbles in a dozen, no matter what you're talking about, a dozen is 12. Same thing for moles.
As the atomic masses of the elements on the periodic table increases what happens to each of the number of atoms in 1 mol of each element?
It is the same. 1 mole is always 23 6.022x10 from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;" It is the same. 1 mole is always 6.022 x (10 to the 23rd) from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;"
What characteristic does one mole of carbon have in common with one mole of sodium?
One mole of carbon and one mole of sodium have exactly the same number of atoms. That is what defines the mole, Avogadro's number, 6,022 X 1023 atoms per mole is the definition of mole.
Why does 10g of nitrogen gas contain the same number of molecules as 10g of carbon molecules?
No, they do NOT contain the same number of particles (either molecules N2 or atoms C): there molecular or atomic mass is different.Look at this:10g N2 / 28 (g/mole N2) x 6.022x1023 (molecules N2/mole N2) = 2.15 x1023 molecules N210g C / 12 (g/mole C) x 6.022x1023 (atoms C/mole C) = 5.02 x1023 atoms C
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
No, a mole of helium gas does not have the same number of molecules as a mole of lead. This is because the number of particles in a mole is determined by Avogadro's number, which is approximately 6.022 x 10^23. Since helium is a monoatomic gas and lead is a solid with a lattice structure, the number of helium atoms in a mole is significantly larger than the number of lead atoms in a mole.
Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.
What contains more molecules a mole of lead or a mole of carbon?
They both have the same number of atoms. The weight is different
What is a mole How is a mole related to Avogadro's number?
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
Which term is same for one mole of oxygen and water?
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
True or false a mole of water in chemistry contains the same number of atoms as a mole of methane?
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
What weighs more hydrogen atoms or carbon atoms?
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
What compare 1 mole of H2 1 mole of O2 and 1 mole of F2?
All contain the same number of atoms: 6,022 140 857(74).10e23 (number of Avogadro).
What does a mole of all known substances have in common?
A mole of any substance contains the same number of particles, bey they atoms, molecules, or formula units.
