1374.75  is the concentration in milligrams per ml of a solution containing 23.5 meq sodium chloride per milliliter.
Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
It is calculated in mg/ml.
The unit of measurement frequently used for electrolytes is the milliequivalent (mEq). This value compares an element's chemical activity, or combining power, to that of 1 mg of hydrogen.
Formula for calculating concentration in mg/ml is
Conc. (mg/ml) = M(eq) /ml ×  Molecular weight / Valency
 
Given 
M(eq) NaCl/ ml = 23.5
Molecular weight pf NaCl = 58.5 g/mol
Valency = 1
Putting the values into the formula 
Conc. (mg/ml) = 23.5 ×58.5/1
                        = 1374.75 mg/ml
Hence, 1374.75  is the concentration in milligrams per ml of a solution containing 23.5 meq sodium chloride per milliliter.

Answer:
In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases of that substance coexist in thermodynamic equilibrium. It is that temperatureand pressure at which the sublimation curve, fusion curve and vaporisation curve meet.
 
        
                    
             
        
        
        
Answer:
3- gamma radiation 
Explanation:
Hello,
In the above question, 4 of the options are related to polymerization which are 
1. Synthetic polymer
2. Natural polymer
3. Condensation polymerization 
4. Addition polymerization. 
The first two options are types of polymer that exists while the last two are polymerization techniques. 
The odd option here which is "gamma radiation" is a particle which is emitted from radioactive substances during decay. It has no mass and no charge but it is highly penetrating and dangerous to human health.
However, 
Synthetic polymers are also known as man made polymers and they exist around us because they're present in materials which we use everyday. An example is polyethylene, nylon-6,6 etc
Natural polymers are compounds which are polymeric in nature (compounds catenating to form a complex molecule). Natrual occurring polymers can be found in proteins and some lipids.
