Answer:
The molecular weight is 
Explanation:
From the question we are told that
The mass of the sample is 
The temperature is 
The volume which the gas occupied is 
The pressure is 
Generally from the ideal gas equation we have that
Here n is the number of moles of the gas while the R is the gas constant with value 
=> 
=> 
Generally the molecular weight is mathematically represented as
=> 
=>
The answer is: [D]: a reactant.

I would say that honestly reporting experimental findings is an example of using good science because science is definitely about honesty in accepting experimental findings and realizing that one has to face up to the consequences and develop things from there rather than wishing the outcome was different.
53 if your talking about electrons. 74 if your talking about neutrons. energy levels=5
Hope this helps☺️
