Its reversible, soluble, <span>mass, density, color, boiling point, temperature, and volume. </span>
It is because sodium is one of the most reactive metals.
There is a reaction would take place between magnesium and sodium chloride.
The chemical reaction between these two metals is given below.
It is Mg + 2NaCl >> MgCl2. + 2Na.
The symbol of this chemical element is Na.
It has the atomic number of eleven
Hope this helps *smiles*
<u>Answer:</u> The molecular weight of protein is 
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

or,

where,
= Osmotic pressure of the solution = 0.0861 atm
i = Van't hoff factor = 1 (for non-electrolytes)
= mass of protein = 400 mg = 0.4 g (Conversion factor: 1 g = 1000 mg)
= molar mass of protein = ?
= Volume of solution = 5.00 mL
R = Gas constant = 
T = temperature of the solution = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
Putting values in above equation, we get:

Hence, the molecular weight of protein is 
I think you meant K as in kilograms?
If so, the answer should be 0.0052.
WHAT THE HECK!?!?!?! AM I SUPPOSE TO KNOW WHATEVER LANGUAGE THAT IS?!?!
