% m/v of the solution = 0.2%m/v
<h3>Further explanation</h3>
![\tt Percent~m/v=\dfrac{mass~solute(g)}{volume~solution(ml)}\times 100\%](https://tex.z-dn.net/?f=%5Ctt%20Percent~m%2Fv%3D%5Cdfrac%7Bmass~solute%28g%29%7D%7Bvolume~solution%28ml%29%7D%5Ctimes%20100%5C%25)
or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate
![\tt \%m/v=\dfrac{20~g}{10,000~ml}\times 100\%\\\\\%m/v=0.2\%](https://tex.z-dn.net/?f=%5Ctt%20%5C%25m%2Fv%3D%5Cdfrac%7B20~g%7D%7B10%2C000~ml%7D%5Ctimes%20100%5C%25%5C%5C%5C%5C%5C%25m%2Fv%3D0.2%5C%25)
I am not completely sure what your question is, but I think you are asking about the molar mass? It is a mole conversion. For example, if you start with atoms and want grams, you would need to get rid of the atoms unit first then get rid of the mols unit: so you would have to multiply it by (1 mol / Avogadro's number) X (molar mass / 1 mol) = this is the conversion factor that gives you grams. I hope this helped!

Answer:
Esters and water are formed when alcohols react with carboxylic acids.
Explanation:
This reaction is called esterification, which is a reversible reaction. This type of reaction is called a condensation reaction, which means that water molecules are eliminated during the reaction. hope this help you :)
The mass percent of a NaCl solution prepared by mixing 47.0 g NaCl with 125.0 Ml of pure water is 27.3%
calculation
% mass =mass of solute / mass of the solvent x 100
mass of the solute(NaCl )= 47 g
mass of the solvent = mass of pure water + mass of NaCl
convert 125 Ml of pure water to grams
that is 1 ml = 1 g therefore 125ml = 125 g
mass of solvent is therefore= 125g+ 47=172g
therefore the % mass = 47/172 x100 = 27.3 %
Explanation and Answer:
This is an opinion based question and there could be many different responses these are just examples of solution to restore the fishery:
-limiting the season during which lobsters can be caught this allows the population to reproduce itself gradually but maintaining it in control
-limiting the amount of lobster that can be caught therefore again letting the population increase
