Reblob this post with a picture of what you use for your Density Lab.

[chemistryblob]

Perform one equation in the set of 22-24 which has you solve for mass

Also perform one equation in the set of 25-27 which has you solve for volume

[chemistryblob]

You will be presented with equivalency formulas. Sometimes you will have to ‘switch around’ the formula in order to solve for the unknown in an equation. 

review the following examples

Complete problem #19 above.

[chemistryblob]

Perform the above conversions for 18g through 16l.

Present each conversion in the same amount of significant digits as shown.

[chemistryblob]

You should be able to identify the number of significant digits in the problems presented under #11a. through 11h above.

These are the rules for significant digits. You will have to follow these rules to know how to provide the same amount of significant digits that were represented in a problem. Basically you should’t present an answer that has a higher accuracy than what was presented in the problem.

You only need to copy down in your notes the numbered parts 1-4 above.

Complete problems 1 through 5 shown here using the Factor label method. 

…or in some way show your work. 4/5 then 5/5 for correction

[chemistryblob]

For this class you will be using something called the Factor Label method. It will seem super simple at first, but it will help later when these equations grow.

For example: you must convert between 1.26 centigrams to milligrams

very simply you will ‘remove’ or ‘X OUT’ the centigrams by changing to grams. then you will ‘remove’  or ‘X OUT’ the grams by changing to milligrams. 

Remember that multiplying a fraction by equivalent statements = in this case 1 over 1 that is to say by 1/1, the equation remains the same. Only the units change.

SI units applies for both solids and liquids and various calculations. 

**Hint: you will need to use this conversion later.
