The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = 
the percentage of heaviest Sn is 5.80%
So the total atoms of
= 5.80% X 
Total atoms of
=
atoms
the mass of
will be = 
The density is 1.12161 g/ml
Answer:
<u>Frederich Miescher</u>- first person to isolate DNA and RNA
<u>Frederick Griffith</u>- first to demonstrate horizontal transmission of dna using bacteria
<u>Gregor Mendel</u>- documented and demonstrated inheritance patterns
Thomas Hunt Morgan- identified chromosomes as the structures responsible for inheritance
<u>Joachim Hammerling</u>- demonstrated that the hereditary information of of eukaryotes is contained within the nucleus
<u>Alfred Hershey and Martha Chase</u>- demonstrated that dna not protein was the molecule responsible for hereditary
<u>George Beadle and Edward Tatum</u>- used mutants to show the relationship between DNA and proteins
<u>Albrecht Kossel</u>- characterized the structure of adenine, guanine, cytosine, thymine, and uracil
Explanation:
Hope this helps! Pls give brainliest!
Im pretty sure it nitric acid
Explanation:
As the charge of all electrons are equal, the repulsive force exerted by each of them is also going to be equal. So, as K has more electrons repulsing its valence electron than Na, it has greater electron shielding.
