Explanation & Answer

Thank you for the opportunity to help you with your question!

1.549 * (556e-10)^3 = 2.662e-22

Multiplying the density by the volume of 1 cube gives the mass of 1 cube.

2.662e-22 / 6.655 ×10-23 

=4

Dividing by the atomic mass gives the answer of 4

Please let me know if you need any clarification. I'm always happy to answer your questions.
