Trere are 4 hydrogen and 2 oxygen.
Two water molecules (2H2O) have four oxygen atoms in total.
There are a total of 15 atoms in 2H2O molecules involving aluminum (Al). Each H2O molecule contains 3 atoms (2 hydrogen and 1 oxygen), so two of these will contain a total of 6 atoms. Aluminum atoms are not present in this molecular formula.
There are a total of 4 hydrogen atoms in 2 molecules of H2O. Each water molecule has 2 hydrogen atoms.
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).

There are 4 atoms of hydrogen in 2H2O.
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).
There are a total of 25 atoms in Na2S2O3.5H2O. This can be calculated by adding the number of atoms present in each element: 2 sodium atoms, 2 sulfur atoms, 3 oxygen atoms, and 18 hydrogen atoms (5 water molecules with 2 hydrogen atoms each).
You multiply the coefficient times the subscripts (number of atoms of each type in the formula) to get the total number of atoms of each element. For example: 2CO2 means 2 carbon atoms and 4 oxygen atoms (No subscript is understood to be 1.) 3C6H12O6 means 18 carbon atoms, 36 hydrogen atoms, 18 oxygen atoms
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
There are 11 atoms in Al2O3: 2 aluminum atoms, abbreviated as Al, and 3 oxygen atoms, represented as O.
There are six hydrogen atoms on the left side of the photosynthesis equation, which is represented by the water molecule (H2O). Each water molecule consists of two hydrogen atoms.
6 Na means 6 atoms of Sodium 6 Na means 6 atoms of Sodium
