About This Simulation
Learn about Avogadro’s number and the relationship between moles, mass and molecular weight as you use the technique of gravimetric analysis to identify an unknown compound.
Learning Objectives
- Explain the relationship between mass, molecular weight, and numbers of atoms or molecules and perform calculations deriving these quantities from one another
- Perform mass-to-mass stoichiometric calculations via conversions to mole
- Identify the limiting and excess reagents in a chemical reaction
- Calculate the theoretical, actual and percent reaction yield
- Define Avogadro’s number and describe the mole quantification of matter

Learn More About This Simulation
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.
Identify an unknown compound
In order to identify a compound where the label has been partly destroyed, you must apply the technique of gravimetric analysis. To do so, you must first learn to understand the relationship between mass, moles and molecular weights and how to perform stoichiometric calculations from mass to mass via mole conversions.
Stoichiometric calculations with moles
You will perform a realistic gravimetric analysis with detailed instructions on what to do and why to do it in every step of the experiment. From balancing the equation to recognizing the stoichiometry of the reactants and finding out which equation to employ in the calculations, the theory behind the experiment is explained step-by-step in the order of the experiment.
What compound is it?
At the end of the simulation, you will have finalized all of the stoichiometric calculations, and the answer to the question should be clear… Can you see what compound it is?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
