Answer:
Explanation:
Remark
CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.
Theoretical mass of CH2
1 C = 1 * 12 = 12
2 H= 2 * 1 = 2
Mass CH2 = 14
The multiplier for CH2
56.108 rounded = 56
Multiplier = molar mass (rounded)/Mass CH2
Multiplier = 56/14 = 4
Chemical
(CH2)_4 = C4H8
Answer: C4H8
1 is D 2 is c 3 is A and 4 the nucleus is so big because it is one of our largest cells in our body... hope this helps!!!!!!!!!!!
