The number of molecules is 3,011.10e23.
If every atomic symbol in a formula has a subscript, simply add the subscripts to find the number of total atoms in the molecule, to produce an answer of 7 in this instance. If there is an atomic symbol without an explicit subscript in the formula, add one more for each such atomic symbol.
There are 7 atoms in N2O5. Therefore, if you have 18 molecules, each with 7 atoms, the total number of atoms is:
7 x 18 = 126 atoms
One molecule of N2O5 contains two atoms of the element nitrogen and five atoms of the element oxygen. There are a total of seven atoms of two different elements in one molecule of N2O5.
5, because it is after the O, which stands for oxygen. The number after the atomic symbol tells how many atoms of that element is in the molecule.

N2O5(g) → 4NO2(g) + O2(g)
1296 g N2O5 x 1 mol N2O5/108 g x 6.02x10^23 molecules/mole = 7.22x10^24 molecules
Ar of N = 14g/mol Ar of O = 16g/mol Mr of N2O5 = 2(14)+5(16) = 108g/mol Using the formula : number of moles = mass / Mr number of moles = 1296g / 108g/mol = 12mol Each mole of substance contains 6.02 x 10^23 particles, therefore 1296g of N2O5 contains 12 x 6.02 x 10^23 = 7.224 x 10^24 molecules.

N2O5(g) → 4NO2(g) + O2(g)
1296 g N2O5 x 1 mol N2O5/108 g x 6.02x10^23 molecules/mole = 7.22x10^24 molecules
1.5 moles of N2O5 Each molecule of NO3 contains one atom of nitrogen, so 3 moles of the compound will contain 3 moles of N atoms. However, N2O5 molecules each contain two nitrogen atoms, so each mole of N2O5 has two moles of nitrogen. So, in order to have three moles of N atoms, you need only 3/2 = 1.5 moles of N2O5.
Ar of N = 14g/mol Ar of O = 16g/mol Mr of N2O5 = 2(14)+5(16) = 108g/mol Using the formula : number of moles = mass / Mr number of moles = 1296g / 108g/mol = 12mol Each mole of substance contains 6.02 x 10^23 particles, therefore 1296g of N2O5 contains 12 x 6.02 x 10^23 = 7.224 x 10^24 molecules.
