Aluminum foil used for storing food weighs about 0.3 g per square inch. How many atoms of aluminum are contained in one square inch of the foil?

The number of atoms of aluminum contained in one square inch of the foil=6

Explanation:

Interpretation:

The number of atoms of aluminum contained in one square inch of the foil is to be calculated.

Concept introduction: relation to calculate a number of atoms contained in one square inch of the foil is given by:

NA/c=mNA/AA1

Where,

M=mass of aluminum

NA = Avogadro's number

AA = Atomic mass of aluminum

Given:

Mass of aluminum foil=0.3 g

M = 0.39g

Relation to calculate a mass of atoms contained in one square inch of the foil is given by:

NA/c = mNA/AA1

M = Mass of aluminum

NA = Avogadro's number

AA = Atomic mass of aluminum

Since,

Avogadro's number

=6
