In each MOLECULE of Pb3PO4 there would be 3 lead atoms, but Pb3PO4 is not a correct formula. The formula for lead phosphate would be Pb3(PO4)2. There are still 3 lead atoms per molecule of the compound.
tetra-ethyl lead means lead and ethyl taken four times in ethyl 7 atoms will be present there fore in tetra ethyl 28 atoms will be present.i9n tetra-ethyl lead 1 lead atom will be present so in total 28+1=29 atoms will be present in tetra-ethyl lead.
Lead nitrate has the chemical formula Pb(NO3)2. This means that each molecule of lead nitrate contains one lead atom (Pb), two nitrogen atoms (N), and six oxygen atoms (O). So, in one molecule of lead nitrate, there are a total of 9 atoms.
Tetraethyl lead has 29 atoms in one molecule.
There are 2 oxygen atoms in 1 molecule of oxygen.
A molecule of serotonin has 26 atoms in total.
A molecule of of water contain 3 atoms.
There are three oxygen atoms in the molecule HNO3.
