How do you count how many atoms of each element in a formula?

Answer 1

You count the little number next to the element and you count how many there are add them together and there you have it. But if you are balancing an equation than you must use those numbers but do not add them together

Answer 2

There are far too many to count. So instead you use the weight of an individual molecule or atom(whatever the item is made of). You then weigh the item or sample and you then know approximately how many atoms/molecules are in the sample.

if given a formula like

FeSO4 you count three elements- Fe, S and O which means that you have a polyatomic

ion and in this case it's called sulfate. The number of atoms of each element are Fe = 1,

S = 1 and O = 4

Answer 3

To count the number of atoms of each element in a formula, you can look at the subscript number next to each element symbol. The subscript indicates the number of atoms of that element in the formula. Multiply the subscript by the number of that element present in the formula to get the total number of atoms.

Answer 4

You measure its mass and divide by its Atomic Mass to get moles. Each mole is about 6.022 x 1023 atoms.

Answer 5

See the chemical formula of a compound. Example: ammonium nitrate
The formula is NH4NO3: two atoms of nitrogen (N), three atoms of oxygen (O), four atoms of hydrogen (H).

Answer 6

The Periodic Table contain 118 chemical elements.

Answer 7

The number of elements in a compound is determined by chemical analysis.

Answer 8

by concentrating on the proton number
