Water (H2O) has 3 atoms in each formula unit.
The number of atoms in two formula units of potassium nitrate is 10.
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.
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!
