In science, we have a name for this, called Avogadro's number, and it describes the number of representative

**particles**in**one mole**of a substance. The inverse**mole**unit tells us**there**are 6.022×1023**particles**of something *per**mole***.

Also know, how do you find the number of particles in 1 mole?

**Key Concepts**

- 1 mole of any substance contains 6.022 × 10
^{23}particles. - 6.022 × 10
^{23}is known as the Avogadro Number or Avogadro Constant and is given the symbol N_{A}^{(}^{1}^{)} - N = n × N
_{A}N = number of particles in the substance. - To find the number of particles, N, in a substance:
- To find the amount of substance in moles, n :

**moles**In and

**gram**. You can view more details on each measurement unit: molecular weight of In or

**grams**The SI base unit for amount of substance is the

**mole**. 1

**mole**is equal to 1

**moles**In, or 114.818

**grams**.

Accordingly, how many particles are in 3 moles?

In chemistry and physics, the Avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole and is equal to 6.02 x 10**23. So 3 moles of carbon atoms would be **18.06** x 10**23.

therefore, 5 moles of oxygen has 6.023*10^**24 atoms**. If number of molecules asked, the above answer is directly written as each molecule contributes to be a particle. therefore , 5 moles of oxygen has **3.0115***10^**24 molecules**.
