5.42 X 10^24 atoms silver ( 1mole Ag/6.022 X 10^23)
= 9.00 moles of silver
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.
Dodecane has 24 hydrogen atoms. The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms. Dodecane has 12 carbon atoms, so it will have 2(12) + 2 = 24 hydrogen atoms.
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.
There are a total of 17 atoms in 3H3PO4. This includes 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 1 carbon atom.
the constant Mole (mol): 6.02 x 10^23 are how many atoms you have per mol so the answer can be 7 mol atoms or 6.02 x 10^23 atoms per mol x 7 actual answer is 4.214 X10^24 atoms in 7 mol

24 atoms in total
2 mol 1.204*10^24=2*6.02*10^23 so the amount is 2 mols
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.
1 Mol of Hydrogen has a mass of 1.0078 grams (g) 1 Hydrogen molecule is 1.673 X 10-24 grams(g) Therefore, if you know how Mols of Hydrogen there are in a solution then you can calculate the number of hydrogen molecules as follows: Example: A Solution has 5 Mols of Hydrogen, How many Hydrogen molecules are there in the solution? answer: 5 X (1.0078g) / 1.673 X 10-24 grams(g) = 3.01 X 1024 atoms
