How many molecules are in 1.64 moles of [tex]Br_2[/tex]?

Answer :

The number of molecules in a certain number of moles can be calculated by multiplying the number of moles by Avogadro's number, which is approximately equal to 6.022 x [tex]10^{23}[/tex].

So, for 1.64 moles of Br2, the number of molecules would be:

1.64 moles × 6.022 x [tex]10^{23}[/tex] molecules/mole = 9.937 x [tex]10^{23}[/tex] molecules

Therefore, 1.64 moles of Br2 would contain approximately 9.937 x [tex]10^{23}[/tex] molecules.

What is Avogadro's number?

The number of atoms, ions, or molecules in one mole of a substance is a key constant in chemistry. Named for the Italian scientist Amedeo Avogadro, it has a definition of 6.02214076 x [tex]10^{23}[/tex] particles per mole. Based on a sample's mass or molar quantity, this number is used to determine the number of atoms, ions, or molecules present. It is crucial for figuring out chemical reactions, putting chemical amounts into perspective, and figuring out how many particles are in a sample. The proportionality factor that connects the number of constituent particles in a sample with the amount of substance in that sample is called the Avogadro constant, often known as NA or L.
