Answer:
Average atomic mass = 58.51047 amu
The symbol is 
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope:
% = 68.274 %
Mass = 57.9353 amu
For second isotope:
% = 26.095 %
Mass = 58.9332 amu
For third isotope:
% = 1.134 %
Mass = 61.9283 amu
For fourth isotope:
% = 3.593 %
Mass = 63.9280 amu
For fifth isotope:
% = 0.904 %
Mass = 63.9280 amu
Thus,
Average atomic mass = 58.51047 amu
The symbol is
Answer:
A substance that protects cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging.
Answer: Heyo Kenji Here! Here's your answer- Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.
Explanation: Hope this helps!
Have a nice day!
