Which of the following processes will determine the number of atoms in a sample? Dividing the mass of the sample by its molar mass
Multiplying the mass of the sample by its molar mass
Dividing the number of moles of the sample by Avogadro's number
Multiplying the number of moles of the sample by Avogadro's number

Multiplying the number of moles of the sample by Avogadro's number

Explanation:

The process that will help determine the number of atoms in a sample is by multiplying the number of moles of the sample by Avogadro's number.

The number of moles of substance has a wide range of application in quantitative chemistry.

A mole of any substance contains the Avogadro's number of particles. The particles can be atoms, molecules, formula units, neutrons, protons, electrons etc.

So, when we have the number of moles of a substance, the number of atoms is obtained by multiplying with the Avogadro's constant.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
