The Chemical equation tells you 3CH4 the first 3 tell you that there are 3 molecules of CH4 CH4 has 1 Carbon and 4 hydrogen (it is called methane) making a total of 5 atoms and there are 3 of them so there is a total of 15 atoms. EDIT (by Dr.J.): Not correct. If there are 3 moles as stated, each mole contains 6.02x10^23 molecules and each MOLECULE contains 5 atoms, so the CORRECT answer is (15)(6.02x10^23) = 9x10^24 atoms
The total number of atoms before and after a chemical reaction is the same.
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
The total number of sodium atoms in 46,0 grams of sodium is 12,044 280.10e23.
There are a total of five atoms in the CH3OH molecule.
The formula is Ca(ClO3)2, so the total number of atoms in the compound is 9.
If you divide the number of atoms of a single isotope by the total number of atoms, you get the ratio of that isotope. This tells you how common/uncommon that isotope is.
There are 6 atoms
5 atoms in that compound
The total number of calcium atoms in 80,0 grams of calcium is 12,044 280.10e23.
Ammonium nitrate molecule has: 2 nitrogen atoms, 4 hydrogen atoms, 3 oxygen atoms.The total number of atoms is 9.
The number and kinds of atoms in the reactants is the same as the number and kind of atoms in the products in a chemical reaction.
There are five atoms in one "formula unit" of limestone. The total number of atoms of course depends on how big a chunk you're talking about.
the total kinetic energy of a substance atoms is the atomic number multiplied by the number of of electrons divided by 3
The total number of atoms in one molecule of Al2(CO3)3 is 14.
The number of atoms is seven.
The total number of atoms in one mole of any substance is 6.02 X 10^23, otherwise known as Avogadro's number.
That's a total of 18 atoms... CO2 = 3 atoms, the 6 indicates there are 6 groups of CO2 atoms in the molecule.
The number of H atoms in 6.37ng of C6H5NO2 are 12 in total.
This number is 50 atoms.
