Part 1. Mole-Particle Conversions
Use the dimensional analysis technique to convert between units. This is a very useful problem-solving skill, and you will use it as often as possible during your Chemistry study.
You will need to know the relationship between the atomic or molar mass and the unit of the initial quantity when performing mole-particle conversions. You will also need to understand the rules for significant figures and be able to express your answers in scientific notation.
The STAAR reference material for Chemistry has a section entitled Constants and Conversions, which is a good place to start your study.
