Question

Answer

The ans is c)mole a) ampere is the unit of currentb)second is the unit of time d) kg is the unit of mass So answer is C) Hope u get it...😄😄😄

Answer

The SI unit for amount of substance is the mole. It has the unit symbol mol. The proportionality constant is the inverse of the Avogadro constant. The mole is defined as the amount of substance that contains an equal number of elementary entities as there are atoms in 12g of the isotope carbon-12.

Answer

Amount of substance is measured in moles

Answer

The correct answer is option 'C', mole.

Explanation:
The unit of amount of substance is called mole. It is a fundamental unit in the International System of Units (SI) and is used to measure the amount of a substance. The mole is defined as the amount of a substance that contains as many elementary entities (such as atoms, molecules, ions, or particles) as there are atoms in exactly 12 grams of carbon-12. This number of elementary entities is known as Avogadro's number and is approximately 6.022 x 10^23.

The mole is used to quantify the number of particles in a sample of a substance, regardless of its mass or volume. It is particularly useful in chemistry, where it allows scientists to easily compare and calculate the amounts of different substances involved in chemical reactions.

Key Points:
- The unit of amount of substance is mole.
- The mole is a fundamental unit in the SI system.
- It is used to measure the amount of a substance.
- The mole is defined as the amount of a substance that contains as many elementary entities as there are atoms in exactly 12 grams of carbon-12.
- Avogadro's number is approximately 6.022 x 10^23, which is the number of elementary entities in one mole of a substance.
- The mole allows scientists to easily compare and calculate the amounts of different substances involved in chemical reactions.
- It is particularly important in chemistry.

In conclusion, the unit of amount of substance is the mole, which is a fundamental unit in the SI system. It allows scientists to quantify the number of particles in a sample of a substance and is particularly important in chemistry.
