Journal Entry:

How will you determine the theoretical percent compostion of your hydrate? How will you determine your experimental percent composition?

Learning Intentions

• You will learn how to review, conduct and modify an experiment using formula mass and percent composition of a hydrate to analyze data and evaluate if a container of a particular hydrate is pure or has been contaminated and is now a mixture.

Closing Task:

You can complete data collection, and then modify plan and analyze data using equations to determine if the hydrate is pure.

Content Standards being covered:

LO 1.2 Students can select and apply mathematical routines to mass data to identify or infer the composition or pure substances and/or mixtures.  

LO 1.3 Students can select and apply mathematical relationships to mass data in order to justify a claim regarding the identify and/or estimated purity of a substance.  

SP 2.2 Students can apply mathematical routines to quantities that describe natural phenomena.    

SP 4.3 Student can collect data using a plan to answer a particular scientific question
