Question

How many atoms of aluminum (Al) are contained in 3.73 moles of alumni

Answer 1

Number of atoms : 2.245 x 10²⁴

Further explanation

A mole is a number of particles(atoms, molecules, ions) in a substance

This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

n= 3.73 moles

Number of atoms :

`\tt 3.73* 6.02* 10^(23)=\boxed{\bold{2.245* 10^(24)}}`
