How many atoms are in Mg3(PO4)2
The answer is 0,0625 mol.
To determine which atoms in a table are of the same element, you would look for atoms that have the same atomic number, as this identifies the element. Atoms of the same element will also have the same number of protons in their nucleus. If isotopes of an element are present, they will have the same atomic number but different mass numbers due to varying numbers of neutrons.
Yes, and the number of protons in the atoms of an element is that element's atomic number on the periodic table.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.

When counting atoms in a chemical formula, each element's symbol is followed by a subscript that indicates the number of atoms of that element present in the molecule. If there is no subscript, it is understood to be one. Parentheses indicate that the atoms within them are multiplied by the subscript outside the parentheses. For example, in the formula ( \text{Ca(OH)}_2 ), there is one calcium atom, two oxygen atoms, and two hydrogen atoms.
The most common element in the universe is hydrogen.
Counting atoms is the process of determining the number of atoms of each element present in a chemical formula or a sample. This involves identifying the elements present, counting the number of atoms of each element, and expressing this information in a chemical formula.
