Working on-board a research vessel somewhere at sea, you have (carefully) isolated 12.5 micrograms (12.5 ×10–6 g) of what you ho
german

Answer:

The value is Z  =  311.33 \ g/mol

Explanation:

From the question we are told that

The mass of saxitoxin is m  =  12.5 mg = 12.5 * 10^{-6} g

The volume of water is V  =  3.10  mL  =  3.10 *10^{-3} L

The osmotic pressure is P =  0.236 =  \frac{0.236}{760}  =  3.105 * 10^{-4} atm

The temperature is T  =  19^oC  =  19 + 273 =  292 \  K

Generally the osmotic pressure is mathematically represented as

P  =  C  *  T  * R

Here R is the gas constant with value

R =  0.0821 ( L .atm /mol. K)

and C is the concentration of saxitoxin

So

3.105 * 10^{-4}  =  C * 0.0821   *  292

C = 1.295 *10^{-5} mol/L

Generally the number of moles of saxitoxin is mathematically represented as

n = C  *  V

=> n = 1.295 *10^{-5}   *3.10 *10^{-3}

=> n = 4.015 *10^{-8} \  mol

Generally the molar mass of saxitoxin is mathematically represented as

Z  =  \frac{m}{n}

=> Z  =  \frac{12.5 * 10^{-6}}{ 4.015 *10^{-8}}

=> Z  =  311.33 \ g/mol

What type of microscope has a magnification less than 300x but allows you to view objects in 3D?
Sindrei [870]
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.
