Answer:
The human body needs a list of macromolecules and micromolecules for performing day to day functions.
The essential macronutrients that the body requires are:
Carbohydrates: Carbohydrates are required by the cells in the body to carry out normal day to day functions. Energy is provided in the form of calories by the carbohydrates.
Proteins: Proteins are essential nutrients which are required for growth as well as better functioning of the immune cells of the body.
Fats and oils: These are needed for providing insulation to the body and to store energy.
Fibres: These are a mixture of carbohydrates.
Water: Almost every activity of the body requires water.
The essential micronutrients that the body requires are:
Vitamins: Vitamins are a group of substances which are needed by the body to function normally.
Minerals: Mineral are needed to ensure that tissues are working correctly.

Explanation:
The given data is as follows.
                = 3 M,
 = 3 M,            = ?
 = ?
                = 10 M,
 = 10 M,          = 10.0 ml
 = 10.0 ml
Therefore, calculate the volume of given solution as follows.
                =
 =  
Now, putting the given values into the above formula as follows.
              =
 =  
              =
 =  
    
                     = 33.3 ml
 = 33.3 ml
or,                             = 0.033 L        (as 1 ml = 0.001 L)
Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml. 
            Molarity = 
                3 M = 
               mass = 3.96 g
Therefore, we can conclude that mass of NaOH is 3.96 g.
