Answer:
Magnesium ribbon
Explanation:
The mole of a substance is a quantity that contains the Avogadro's number of particles.
This Avogadro's number of particles = 6.02 x 10²³particles
It is known that 1 mole of any substance contains 6.02 x 10²³particles
So, from the given choices, the object with the highest number of moles will contain the highest amount of particles.
Magnesium ribbon with 0.871mole will contain the highest number of particles;
Number of particles = 0.871 x 6.02 x 10²³particles = 5.24 x 10²³particles
