VIDEO: PRACTICE TEST PROBLEMS

In this VIDEO, Mr. Hatfield demonstrates the various kinds of calculation problems found on the Practice Test shared with students through their Microsoft Teams channel.

That includes the use of molar masses and conversion problems involving moles, grams, liters and number of particles, as previously taught last semester and reviewed HERE.  This material is covered in the text in sections 8.1 - 8.2 (pg. 262-279).

Calculations introduced this semester include percent composition, empirical and molecular formulas (Section 8.3, pg. 280-289) and molarity and dilution problems (Section 8.4, pg. 292-299).

A separate video will be made available to cover the conceptual material presented in this course since the beginning of the semester.
