This week's main post requires two parts, reviewing a related mathematical problem and describing a common chemical.

In chapter 1, we reviewed many fundamentals for General Chemistry, please initiate and participate in the reviews of the mathematical-related topics as the first part of this week's review. We want to use this review to improve the mathematical skills of the whole class. 50% of this week's discussion grades will be assigned to this topic. Therefore, please try your best. Your focus should be on how to solve a very specific question. For example, how to establish a conversion factor and use it to convert one unit to another.

-Measurements

-Units

-Scientific notation

-Significant figures

-Dimensional analysis

-Any mathematical skills that could be required for this class.
