Explanation:
From the question we are told that:
Slope 
initial Concentration 
Time 
Generally the equation for Raw law is mathematically given by



Organic molecules typically do not contain the noble gases, so they would contain all but Ne
As has an atomic number of 33, so it has 33 protons.
It has a charge of 3-, so there are three more electrons than protons. Thus, there are 36 electrons.
It has a mass of 75, which is the sum of neutrons and protons.
33+n=75 ---> n = 75 - 33 = 42 neutrons
The answer is e) 33 protons, 42 neutrons and 36 electrons.
