Expert Answer

Step 1

The concentration of any substance can be expressed in different ways such as molality, molarity, normality etc. Some other ways are ppm, ppb, mole fraction and mass percentage.

Step 2

1 mole of any substance contains 6.022 x 1023 atoms or molecules or particles. Here 6.022 x 1023 is known as Avogadro number.

Step 3

Mass of glycine = 3.06 x 10-3g

Molar mass of glycine = 75.0...
