The atomic weight of copper is 63.5. What will be the total number of gram atoms and number of atoms present in 100 gram of copper?

Given :

The atomic weight of copper is 63.5 gm.

To Find :

The total number  of gram atoms and number of atoms present in 100 gram of copper.

Solution :

We know, 1 gram atom is equal to mass of one mole of copper i.e. 63.5 gm.

So, number of gram atom in 100 gram of copper is :

n = 100/63.5

n = 1.57 gram atom

Now, number of atoms on gram atom is :

Therefore, total number  of gram atoms and number of atoms present in 100 gram of copper is 1.57 gram atom and .

Hence, this is the required solution.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
