How many iron atoms are there in 2.50moles of each of the following? fewo4 =? atoms of fe

There are 1.505 .10²⁴ iron atoms in 2.5 moles Wolframite (FeWO₄)

Stoichiometry in Chemistry learn about chemicals mainly emphasizes quantitative, such as the calculation of volume, mass, number, which is related to numbers, molecules, elements, etc.

The empirical formula (EF) is the smallest atomic ratio of the constituent elements.

The empirical formula shows the simplest comparison of the atoms making up the molecule

Molecular formula (MF) is a formula that shows the number of atomic elements that make up a compound.

(EF)n = MF

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

1 mole = 6.02.10²³ particles

While the number of moles can also be obtained by dividing the mass (in grams) with

In the Wolframite( FeWO₄) compound there is 1 mole of Fe atom from 1 mole of FeWO₄ molecule

So if there are 2.5 moles of FeWO₄, the number of Fe moles is the same as 2.5 moles of Fe

Then the number of Fe atom particles in 2.5 mol Fe is:

2.5 x 6.02.10²³ particles  = 1.505 .10²⁴ iron atoms

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

i just learnt this recently but i need to look through my notes again
