There are six.
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms
Mg(NO3)2 is magnesium nitrate and it is not an element, but is a compound. Each molecule has 1 Mg atom + 2 N atoms + 6 O atoms for a total of 9 atoms per molecule. The more molecules you have, the more atoms you have.
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
25 atoms
The number of atoms is seven.
6 carbon atoms.12 hydrogen atoms.6 oxygen atoms---------------------------------add= 24 total atoms============
The total number of atoms of the reactants should be equal to the total number of atoms of the products. The total number of molecules of the reactants should be equal to the total numbers of molecules of the products
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.
9 atoms
This number is 50 atoms.
