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
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 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 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 atoms are in a molecule of borax Na2B4O7?
13 atoms are in one molecule of borax but that is surrounded by 10 water of hydration molecules containing 3 atoms each; giving a total of 43 atoms altogether in and around one borax molecule.
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.
Which contains the most molecule's 1 mole of water 1 mole of glucose or 1 mole sodium chloride?
If you like that question, you would probably also like this one: Which has the greatest number of items: A bag of a dozen donuts, a box of a dozen apples or a carton of (a dozen) eggs.By definition, "one mole of" could also be phrased as "one Avagadro's number of" ... Since that number is a constant, all three have the same number of molecules. Avogadro's numberis the number of atoms or molecules in a mole.Since all molecules don't weigh the same, the molecular weight corresponds to that difference in mass.Avogadro's number (a.k.a. Avogadro's constant) is very large, 6.0221415 × 1023to quantify things that are generally very small. Generally molecules, atoms or particles.
What is the Avogadro's number for water?
Each molecule of H2O contains three atoms. Avogadro's number of water molecules constitutes about 18 grams; therefore one-third of this mass, or 6 grams, will contain the stated number of atoms.

How many atoms are in 2.4 moles of hydrogen?
This is how you solve it you use Avagoadro's constant which is 6.022 X1023this number is not showing up correctly here. It is supposed to be 6.022 X 10 to the 23 power.This is the number of atoms per mole of a molecule. Just like you have 12 eggs in a dozen. For example how many eggs would 2.4 dozen eggs have. 2.4 X 12 = 28.8 eggs.So in the following problem the moles will cancel each other out and give you the number of atoms. I would calculate for you but I don't have my calculator on me, but this is how you set it up.2.4 mole Zn X 6.022 X10 23 atoms/mole

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.
