Answer:
[tex]1.2\times10^2^4[/tex] particles in 2 moles.
Explanation:
The number of particles that are contained in one mole, the international unit of amount of substance: by definition, exactly 6.022×10²³, and it is dimensionless. It is named after the scientist Amedeo Avogadro.
It is also known as Avogadro's constant.
∴ Number of particles in one mole = [tex]6.022\times10^2^3[/tex]
∴ Number of particles in 2 mole = 2 times Number of particles in one mole
∴ Number of particles in 2 mole=[tex]2\times6.022\times10^2^3=12.044\times10^2^3\approx1.2\times10^2^4[/tex]
Hence there are [tex]1.2\times10^2^4[/tex] particles in 2 moles.
