Sections 1 & 2: Under homework docs, you will find the case study you must complete, on loose-leaf, by next Thursday. You will also need the information in this photo (the ruler reads 8 in)....

Section 3: Complete the worksheet you started for homework last night.
Here's an example of a mass to mass conversion problem (#5B):

Section 6: Answer the following questions on a piece of loose-leaf paper: 

1. Calculate the mass, in grams, of 5.00 mol lead oxide (PbO)     

2. Calculate the number of molecules in 0.700 g sodium bromide (NaBr)   

3. Calculate the amount of grams in 0.950 mol hydrogen sulfide (H₂S)

4. Calculate the number of molecules in 6.00 mol beryllium fluoride (BeF)  

5. Given the following equation: 2 K + Cl2 ---> 2 KCl

a. How many grams of KCl is produced from 2.50 g of K and excess Cl2 ?

b. How many grams of KCl is produced from 1.00 g of Cl2 and excess K ?

6. Given the following equation: Na2O + H2O ---> 2 NaOH

a. How many grams of NaOH is produced from 1.20 x 102 grams of Na2O?

b How many grams of Na2O are required to produce 1.60 x 102 grams of NaOH?
