A Pb nucleus with an atomic mass of 206 contains 82 protons (from the atomic number of lead) and 124 neutrons (subtracting the atomic number from the atomic mass).
For this you need the atomic mass of Pb. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel..0015 moles Pb × (207.2 grams) = .311 grams Pb
Lead is a metal element. Atomic Mass number of it is 207.
The atomic weight of gold (Au) is approximately 197, and the atomic weight of lead (Pb) is approximately 207.
The number of neutrons in an atom of lead (Pb) can vary depending on the isotope of lead. The most common isotope, lead-208, has 82 neutrons.
To find the molar mass of lead (II) nitrate (Pb(NO3)2), you first calculate the individual atomic masses of each element in the compound (Pb, N, O). Then, add up the atomic masses of each element based on the subscripts in the formula (2 nitrogens and 6 oxygens in this case) to get the molar mass. In this case, the molar mass of Pb(NO3)2 would be 331.2 g/mol.
