Question

How many moles of tin,Sn, are in 2500 atoms of tin?

Answer 1

Answer:

4.15×10⁻²¹ moles of Sn

Explanation:

This question can be solved by a simple rule of three.

We know that 1 mol contains 6.02×10²³ particles.

In this case, our particles are the atoms, so:

6.02×10²³ atoms / 1 mol . 2500 atoms = 4.15×10⁻²¹ moles.

The knowledge of mol can be applied for everything:

A mol of molecules

A mol of atoms

A mol of a compound
