Hint: The determination of the amount of any matter is an important aspect of laboratory practices or even in our day to day lives as it provides a prominent idea about the quantity of a substance and hence could be consumed accordingly.

Complete step-by-step answer:The amount of any substance can be determined by the help of a proper scale which is different for different states of matter.
For an instance, the amount of a liquid substance can be determined by using the scale of millilitre or litre. So, when we say five litres of water, we know how much water would weigh five litres. Similarly in case of solids the amount could be determined by using gram or kilogram units and we know how much the amount would weigh one gram. These are the basic scales for determination of the amount of any substance.
However there are some of the quantities which are individual in nature and cannot be expressed in terms of any other quantities and such quantities are called fundamental quantities. The amount of a substance can also be expressed in terms of moles and it is also a fundamental quantity. One mole of any substance would contain a specific number of particles which is called the Avogadro’s number.

Note:The amount of a substance can be determined by using the information of the state of that matter then choosing an appropriate scale to measure the amount of the substance.
The solid substances can be weighed by the use of kilogram or gram scale, and the amount of liquid substance can be determined by using the litre or millilitre scale.
