Answer:
1-Ethyl-3-methylidenecyclopentane
Step-by-step explanation:
Formula = C₈H₁₄. An alkane has formula C₈H₁₈. ∴ X contains 2 double bonds, 2 rings, or 1 ring and 1 double bond.
X absorbs only 1 mol of hydrogen. ∴ X contains 1 ring and 1 double bond.
Hydrogenation gives 1-ethyl-3-methylcyclopentane.
Ozonolysis gives formaldehyde, so X must contain a =CH₂ group.
Hydrogenation of X converted the =CH₂ to -CH₃.
X is 1-ethyl-3-methylidenecyclopentane.

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
