This is how you solve it you use Avagoadro's constant which is 6.022 X1023
this 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

∙ 12y ago2.4 mole hydrogen (6.022 X 10^23/1 mole H) x 2 atoms of hydrogen per mole of H2
= 2.8 X 10^24 atoms of hydrogen
--------------------------------------------------wrong!!!
Whoever " corrected this is wrong. A mole of H, or H2 is still a mole and designation of that in the conversions mean nothing.
2.4 mole hydrogen ( in gaseous form ) (6.022 X 10^23/1 mole H2)
= 1.4 X 10^24 atoms of hydrogen
------------------------------------------------correct!
--------------------------------------------( no 2 atoms of hydrogen per mole H2!! )

∙ 15y agoFor this problem, the Atomic Mass is not required. Take the mass in moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for the units to cancel.
2.4 moles H2 × (6.02 × 1023 atoms) = 1.44 × 1024 atoms

∙ 13y ago1 mol is about 6.022 x 1023 atoms so 2.4 mol is 1.44528 x 1024 atoms.... I think! Its a lot anyway.

So 2 moles will weigh 18.024 g

∙ 12y agoSince hydrogen exists normally as diatomic molecules, the answer is 2 X 2.4 X Avogadro's Number or 2.9 X 1024 atoms, to the justified number of significant digits.

So 2.4 g will have 1.205 x 1023 atoms or 0.2 mole of atom

How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
How many atoms of hydrogen are found in 5.29 mol of heptane C7H16?
1,36 moles C5H12 (12 moles H/1 mole C5H12)(6.022 X 10^23/1 mole H) = 9.83 X 10^24 atoms of hydrogen
How many atoms of hydrogen are present in 2.32 mols of C2H4?
One Mole of C2H4 will containt 6.0221415×10^23 molecules of C2H4. Therefore 2.23 Moles of C2H4 will contain 1.39713683x10^24 molecules of C2H4. There are 4 Hydrogen atoms in C2H4, so 1.39713683x10^24 x 4 = 5.58854732X10^25 atoms of hydrogen.
How many moles of oxygen are in one mole of P4O10?
10 moles of oxygen atoms or 5 moles of oxygen molecules.
How many hydrogen atoms are in 2C6H1206?
To answer this kind of question, multiply the coefficient, 2, by the subscript after the atomic symbol for hydrogen, H, to obtain 24 hydrogen atoms.

How many moles of hydrogen are in 0.80moles of quinine?
You can figure this question out by looking up quinine to find its chemical formula. The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.
