Question

The number of atoms in 2.50 mol Cr

Answer 1

Answer:

1.51 x 10²⁴atoms

Explanation:

Given parameters:

Number of moles of Cr = 2.50mol

Solution;

what is a mole;

  a mole of any substance is the amount of substance that contains the avogadro's number of particles which is 6.02 x 10²³ particles

The particles here can be atoms, protons, neutrons, electrons e.t.c

                   1 mole contains 6.02 x 10²³ atoms

                  2.5 moles will contain  2.5 x 6.02 x 10²³   = 1.51 x 10²⁴atoms
