Answer:
Answer is option B.
The first book made for coroners is The Washing Away of Wrongs.
Explanation:
The Washing Away of Wrongs (or Collected Cases of Injustice Rectified) is an ancient Chinese book. It was written by Song Ci and printed in 1247, during the Song Dynasty as a handbook for coroners. It is considered as the oldest book on forensic medicine. This book describes many historical cases of forensic science, most of them were experienced by the author. The book contains detailed notes on post-mortem examinations, methods of treatments to certain injuries, appearances of corpses from various causes of death.
Answer:
63.55 amu
Explanation:
The average atomic mass of an element can be calculated by multiplying the decimal abundance of each isotope of that element by the relative atomic mass and summing them up. That is;
Average atomic mass = {atomic mass of isotope 1 × decimal abundance of Isotope 1} + {atomic mass of isotope 2 × decimal abundance of isotope 2}
According to this question, two most abundant isotopes of copper contain 34 and 36 neutrons. The atomic mass of each isotope can be found by adding the no. of neutrons to the atomic number/proton no., which is 29.
Atomic mass of Isotope 1= 34 + 29 = 63
Atomic mass of Isotope 2= 36 + 29 =65
Decimal abundance of each isotope = percentage abundance ÷ 100
Isotope 1 (with 34 neutrons) = 72.5% = 72.5/100 = 0.725
Isotope 2 (with 36 neutrons) = 100 - 72.5 = 27.5% = 27.5/100 = 0.275
Therefore, the average atomic mass
= {63 × 0.725} + {65 × 0.275}
= {45.675} + {17.875}
= 63.55
Hence, the average atomic mass of copper is 63.55 amu
