Answer: 208 g/mol and 87 g/mol
Explanation: We are given the units as 'g/mol' which are the units of atomic mass.
Atomic mass is the sum of number of protons and number of neutrons.
Atomic number = Number of protons + Number of neutrons
For [tex]^{208}Pb[/tex]
Number of neutrons = 126
Number of protons = 82
Atomic mass = 126 + 82 = 208 g/mol
For [tex]^{87}Sr[/tex]
Number of neutrons = 49
Number of protons = 38
Atomic Mass = 49 + 38 = 87 g/mol
Answer:
The isotope lead-208 (208Pb): 208 g/mol The isotope strontium-87 (87Sr): 87 g/mol
