Why do different masses of the elements have the same avagadro's number of particles?
Try to think of an Avagadro number (1 mole) as being a unit similar to --- say a dozen. 1 dozen eggs has 12 "particles" 1 dozen baseballs has 12 "particles" 1 dozen footballs has 12 "particles" So all three of above have 1 dozen "units". It is the same with an Avagadro number - all with 6.022 x 1023 units. However just as all three examples above have different masses yet all are one dozen. It is the same with an Avagadro number (or 1 mole. ) So 1 mole of hydrogen molecules has a mass of 2g but 1 mole of Uranium atoms has a mass of 238g (because they are much bigger in the same way as a football is bigger than an egg).
Does the mass of the atom effect the size of the mole?
A mole represents a number of Avogadro's Constant. It is same as naming 12 units a dozen. It is not related with the weight of atoms, molecules, ions or compounds.
How many molecules are in 0.0600 mol NH3 Answer in units of molec?
There are 3.613x1022 molecules in 0.0600 moles of NH3A mole of anything is 6.022x1023 of it(just like a dozen of something is a set of 12).Definition of a mole:A mole is the amount of a substance that contains of entities (atoms or ions or molecules,etc.) as there are atoms in 0.012kg of carbon 12. This amount-called Avogadro's number- is 6.022 × 1023.Finding the answer:A mole of NH3 molecules contains 6.022x10^23 molecules ; therefore,number of molecules = (6.022x10^23) x (number of moles)= (6.022x1023 ) x (0.06)= 3.613x1022 molecules
Does one mole of copper contain an amount of copper atoms equal to avogadros number?
Yes, it does: 1mol Cu = 6.02*10^23 atoms (you can look at this as molecules to make it easier) 1mol H2 = 6.02*10^23 molecules - which is the same (dont get it confused, as H2 has 1.204*10^24 ATOMS, but the question expicitly asks for molecules) Yes, it does, though you might wish to say "atoms" to replace "molecules" as the question is written. A mole of any one thing will have an equal number of "particles" (atoms or molecules, depending on the substance) as a mole of something else. The mole (about 6.02 x 1023) is a large number, but one that is very effectively applied across a range of chemical activities to quantify some amount of a substance we might be using or investigating.
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).
Does one mole of hydrogen have the same numbers of atoms as one mole of chlorine?
A mole is just a number, like a dozen, but a lot bigger. So the question is like asking "Does a box of a dozen small eggs have the same number of eggs as a box of a dozen jumbo eggs?" (Yes, they both have a dozen, 12, eggs. They both have Avogadro's number of molecules.) Trick question: a mole is a count of molecules, not atoms. A mole of water would have half again as many ATOMs as a mole of oxygen, since water comes 3 atoms to the molecule, but oxygen as O2 has 2 atoms per molecule. Similarly a dozen breakfasts of 3-egg omelets would have half again as many eggs as a dozen breakfasts of 2 fried eggs.

How many atoms does a carbohydrate have?
Carbohydrate molecules are compounds of carbon, hydrogen, and oxygen atoms in various proportions.
How many atoms are there in 2 moles of hydrogen?
In 1 mole of anything there is 6.022 x 10^23 of that item. In 1 mole of chairs there is 6.022 x10^23 chairs. In 1 mole of bacteria there is 6.022 x 10^23 bacteria. Likewise, 1 mole of hydrogen atoms is equivalent to 6.022x10^23 hydrogen atoms. 2 moles of hydrogen atoms is double this amount. 2 x 6.022 x 10^23 = 12.044 x 10^23, which is 1.2044 x 10^24 hydrogen atoms. This number, 6.022 x 10^23, is called Avogadro's Number. It is like the word "dozen", which means "12 of". 1 dozen bagels is 12 bagels. 1 dozen animals is 12 animals. Same concept here. Hope that helps ya.
How many hydrogen atoms are there in a fat molecule?
It depends on the specific type of fat molecule. On average, a typical fat molecule contains about 3 to 4 hydrogen atoms for each carbon atom. This means that a fat molecule can have several dozen hydrogen atoms.
What does 12H2O mean?
Ah, 12H2O means there are 12 water molecules present. Imagine each H2O as a little happy water droplet dancing together in a group of 12, creating a beautiful symphony of hydration. It's nature's way of reminding us of the simple joys found in chemistry.

How many atoms are in a molecule of borax Na2B4O7?
A molecule of borax, Na2B4O7, contains a total of 13 atoms. This can be calculated by adding the number of each type of atom present in the molecule: 2 sodium atoms (Na), 4 boron atoms (B), and 7 oxygen atoms (O), for a total of 13 atoms. Each element's subscript in the chemical formula indicates the number of atoms of that element in the molecule.
What is the Avogadro's number for water?
The Avogadro's number represents the number of particles, such as molecules or atoms, in one mole of a substance. For water (H2O), the Avogadro's number is approximately 6.022 x 10^23, which means that one mole of water contains 6.022 x 10^23 water molecules.
Are numbers endless?
No, they are not. Mozen, way after dozen, is the last number. Dozen is 10000000000. Mozen is a huge 1000000000000000000000000000000000000000000000. They are about one-mozen atoms in the Universe.
