Water (H2O) has 3 atoms in each formula unit.
To calculate the number of atoms in 4K3PO4, you would need to consider the subscripts in the chemical formula. For 4K3PO4: 4 molecules would give you 4 x 3 = 12 potassium atoms (K) 4 molecules would give you 4 x 1 = 4 phosphorus atoms (P) 4 molecules would give you 4 x 4 = 16 oxygen atoms (O) Therefore, a total of 32 atoms are present in 4K3PO4.
The number of atoms in two formula units of potassium nitrate is 10.
There are 2 oxygen atoms in a formula unit of sodium acetate (NaC2H3O2).
There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
There's only 1 because the N does not have a subscript stating otherwise!
