please answer this
You have an unknown element consisting of two isotopes, one with mass = 36.9659 amu (24.22%), and one with mass = 34.9688 amu (75.78%). a. Use the weighted average calculation to obtain the atomic mass (weighted average). Show your calculations. Give final answer in 4 significant digits. b. What is the name of the element? c. What is the atomic symbol? d. Draw a similar table and fill in the table for the two isotopes. Please write Isotopes in the following format: = of Neutrons (no decimal numbers) Atomic Number # of Electrons Atomic Mass (no decimals) Isotope # of Protons ick Cancel to quit.
