Did you know that there are more water molecules in a glass of water

Did you know that there are more water molecules in a glass of water than there are sand grains in the Sahara desert? In this simulation, you will learn about the relationship between mass, molecular weight, and the number of atoms or molecules and you will understand the magnitude and importance of Avogadro’s number.
Research and answer the following questions:
What is the relationship between mass, moles, and molecular weights?
What is the unknown compound from the simulation and how did you determine the identity of the unknown compound? Describe the steps.
What is a possible scenario where a nurse may need to use stoichiometric calculations?
This assignment should be 2–3 double-spaced pages in APA (7th ed.) format and have at least one outside resource. Be sure to cite your resources.
