Essential nutrients
These are the organic compounds present in the food that provide nourishment essential for the development and growth of our body. Nutrients not only provide us with the required energy to carry out various biological processes but are also the building blocks for repair and growth in our bodies.
Vitamins
The vitamins are organic molecules required in low concentration for the proper functioning of the body. They cannot be generated in the organism and are taken into the body through the diet. The lack of proper vitamins results in diverse deficiency disorders. They are thus called essential nutrients. The important vitamins are vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin K, and vitamin E.
Make 800 ml of a 1X stock of lemonade from a 6X concentrated stock of frozen concentrate.
The number in front of X is the n- fold dilution to prepare a 1X working solution.
Formula for dilution :
M1V1 = M2V
where, M1 = Concentration of working solution ( 800 ml of 1X stock of lemonade)
V1 = Volume
M2 = Concentration of stock solution (25X stock of frozen concentrate)
V2 = Volume to be find
Now by putting values of M1, V1, and M2 in the dilution equation we get,
M1V1 = M2V2
1 × 800 ml = 6 × V2
V2= 800/ 6
V2= 133.33 ml
