Does 0.25 mole of o2 contain the same number of molecules as 0.25 mole of nh3?
No, 0.25 moles of O2 contains fewer molecules than 0.25 moles of NH3. This is because O2 is a diatomic molecule (Oxygen exists as O2), whereas NH3 is a triatomic molecule (Nitrogen exists as NH3). Thus, NH3 has more atoms per molecule compared to O2.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
How many atoms are in 1.00 mole of molecules if each molecule contains 5 atoms?
One mole of particles is indicated by Avogadro's number of 6.02x10^23. In this equation we have one mole of molecules, each containing 5 atoms. This equation is thus solved by multiplying Avogadro's number by five which equals 3.01x10^24 atoms.
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;"
How many atoms are in a molecule of CCl4?
C = 12 grams/mole Cl = 35.45 grams/mole CCl4 = 12 + (35.45)x4 = 153.8 grams/mole 153.8 grams/mole / 6.022 x 1023 things/mole = 25.4 x 10-23 grams/thing where thing in this case would be a molecule of CCl4
Does carbon dioxide represent a mole or a molecule?
A molecule.
Is the mass of 1 mole of oxygen and 1 mole of S same?
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
Is the moles of atom and moles of molecule is same?
No, the moles of an atom and the moles of a molecule are not the same. A mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. In the case of an atom, this corresponds to one mole of atoms. In the case of a molecule, this corresponds to one mole of molecules.
What is the root word for molecule?
the root word for molecule is mole
Can a mole represent a molecule?
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
What is the mass of 0.256 molecule of water?
0.256 molecule of anything does not exist. The smallest representation of any compound is 1 molecule. If you mean 0.256 mole then: 0.256 mole x (18 g / mole) = 4.608 grams
What is the molar mass of a molecule that weighs 1 dalton per mole?
The molar mass of a molecule that weighs 1 dalton per mole is 1 gram per mole.
How many grams of the molecule C12O16H1 would be equal to 1 mole of the molecule?
In every mole there are only 6.023X1023 molecules irrespective of the compound.
What is bigger mole or molecule?
1 gram of any sample contains 1 mole of molecules. No it is NOT , it's only true for protons!Two or more atoms of same kind come together to form a molecule.Mole is a unit that is used repeatedly in introductory chemistry classes.Added:a molecule is a group of chemically bonded atoms.a mole is a number, like a dozen is 12, a mole is 6.022 x 10^23 , (6.022 x 1023). Eg. 1.0 grams of H2 is equal to 0.5 mole H2 and it contains 3.011 x 1023 H2 moleculesand 1.0 grams of O2 is equal to 0.03125 mole O2, it contains 1.882 x 1022 O2 molecules
What is a mole atom?
A mole, in terms of chemistry usually, represents a number. That number is about 6.022 x 10^23. So when you have a mole of something, you have 6.022 x 10^23 of something. Moles are used in chemisty because the mass of a mole of any molecule in grams is the same as the atomic mass of the molecule in amu's.
How many moles of hydrogen gas could be produced by the complete decomposition of 1 mole of water?
Since a water molecule, H2O, has exactly the same quantity of hydrogen atoms as a hydrogen molecule, H2, it follows that one mole of water can be decomposed into one mole of hydrogen gas.
Why one mole of hydrogen and one mole of H-atom have different masses?
The hydrogen molecule is diatomic, H2.
