Review Constants Periodic Table Part A Atomic mass is a weighted average of the masses of the naturally occurring isotopes of that element. For example, consider isotopes of lithium: Abundance Mass Isotope (%) (amu) Li 7.5 6.015 On a mission to a newly discovered planet, an astronaut finds copper abundances of 69.15 % for Cu and 30.85 % for 65Cu. What is the atomic mass of copper for this location? The mass of Cu is 62.9300 amu . The mass...
what is the atomic mass of copper with isotopes copper - 63 with a mass of 62.930 and copper -65 with mass of 64.928 and percent abundance of 69.17 and 30.83% respectively
Question 4 2 pts What is the average atomic mass of the element that has the following isotopes? 0.005% is of mass 234.040947 amu 0.720% is of mass 235.043924 amu 99.275% is of mass 238.050784 amu Once you find the average atomic mass, please find which element on the periodic table has that mass.

The hypothetical element Q has an atomic weight of 124.8 AMU in the periodic table and only has two stable isotopes. Q isotope 1 has an abundance of 55.83 % and an isotopic mass of 122.16 AMU. What is the mass of Q isotope in AMU ? Round 3 decimal places.
The atomic mass of ^63Cu is 62.9296 amu and the atomic mass of ^65Cu is 64.9278 amu. In a natural sample, 69.10% of the atoms are ^63Cu, and 30.90% are ^65Cu. Calculate a value for the molar mass of copper in g mol-1, given one atomic mass unit (amu or u) equals 1.66054x10^-24g.
copper has an atomic weight of 63.55u. if 69.17% of Cu exists as Cu-63 ( 62.93960u ), what is the identity and the atomic mass of the isotope? a. Cu-64; 64.16u b. Cu-65; 64.16u c. Cu-66; 65.91u d. Cu-65; 64.92u e. Cu-64; 63.82u please tell me which answer it is and why
Copper has two naturally occurring isotopes. Cu-63 has a mass of 62.939 amu and a relative abundance of 69.17%. Use the atomic mass of copper to determine the mass of the other copper isotope. Express your answer using four significant figures.
