## About This Quiz & Worksheet

It would be impractical to work on problems about quantities of atoms if you had to do so in single units of atoms. Thus, this worksheet-quiz set has been assembled to assess your ability to work in units of moles.

## Quiz & Worksheet Goals

Evaluate your knowledge and skills with questions on the following:

• Converting between individual units and moles
• Using moles to convert between measures of mass and the number of atoms in a sample
• Converting between moles and measures of mass

## Skills Practiced

Use these assessments to also practice:

• Critical thinking - apply relevant concepts to examine information about the quantity of samples in a different light
• Interpreting information - verify that you can read information regarding moles and interpret it correctly
• Problem solving - use acquired knowledge to convert the quantity of a sample into different units

## Additional Learning

Review the lesson that comes with this worksheet and quiz, titled Avogadro's Number: Using the Mole to Count Atoms, to improve your abilities working with moles. The objective of this review is for you to:

• Understand the concept of a mole
• Be able to convert between moles and the number of units (atoms)
• Be able to convert between moles and measures of mass
