Stoichiometric Calculations: Identify a compound using gravimetric analysis

In this simulation, you will learn how to correlate mass, molecular weight and number of moles and apply these concepts to perform a gravimetric analysis.

Remember that you can access the theory section at any moment in your LabPad while playing the simulation.

Following is a list of all the relevant theory pages to boost your learning:

• The alkaline earth metals
• The chemical equation
  • How to balance a chemical equation
  • Reaction stoichiometry
• Gravimetric analysis
  • Analyte
  • Counter-ion
• Avogadro’s number and the concept of moles
  • How to count molecules
  • Atomic mass
• Calculating molecular weights
• The relationship between M, m and n
• Limiting and excess reagents
• Theoretical, experimental and percentage yield
• Conversion between moles and molarity
• Experimental thoroughness and accuracy
  • Contamination with other chemicals
  • Causes for deviating yields
• Steps in performing a suction filtration
