Answer:
The value is 
Explanation:
From the question we are told that
The mass of saxitoxin is 
The volume of water is 
The osmotic pressure is 
The temperature is 
Generally the osmotic pressure is mathematically represented as

Here R is the gas constant with value

and C is the concentration of saxitoxin
So


Generally the number of moles of saxitoxin is mathematically represented as

=> 
=> 
Generally the molar mass of saxitoxin is mathematically represented as

=> 
=> 
The Stereo microscope, also called a dissecting microscope, has two optical paths at slightly different angles allowing the image to be viewed three-dimensionally under the lenses. Stereo microscopes magnify at low power, typically between 10X and 200X.
