Content Standards being covered:
Student can identify metric units for common measurements
using in Chemistry and understand how to make conversions using metric system.
23. In scientific notation, large numbers have a power of 10 with a positive
superscript and smaller numbers (decimals) have a power of 10 with negative
superscripts
24. Conversions are set up using dimensional analysis or factor label method
where conversion factors are set up to cancel units until desired unit is
achieved.
*Student understands what a mole of particles is and how the
mole is used in chemistry to determine mass of a compound.
105. The mole is a quantity used to count particles and is equal to 6.022 X
