Mass of filter paper+ PbI₂	3g
Mass of filter paper	0.52g
Mass of PbI₂	2.48g

Mass(g) Pb(NO₃)₂	Mass(g) KI	Mass(g) PbI₂	Moles Pb(NO₃)₂	Moles KI	Moles PbI₂
1.66g	2g	2.48g	5x10^-3	0.012	6x10^-3

The above are the data.

a) using the equation for the reaction ( Pb(NO₃)₂+2KI --> PbI₂ + 2KNO₃ ), calculate how much solid PbI₂ you should have made. This called theoretical Yield.

b) compare your actual results ( the mass of PbI₂ you made) with the theoretical yield ( the mass of PbI₂ you should have made). Calculate % yield.

The mass of an empty filter crucible is 24.1 g. After collecting a precipitate, the crucible mass increases to 26.5 g. The balance measurement error is plus or minus 0.004 g. What is the ERROR in the calculated mass of the precipitate (i.e. mass of crucible + precipitate - mass of crucible)? Report your answer in grams.

The students swabbed each plate and set a filter paper disk with 10% bleach solution of differing ages on the plates for 10 minutes. The disks were removed and then the plates were incubated for 48 hours. The diameter of clearing was measured for each plate. Create a Table, with title, in the results and then interpret the results in the discussion. Notice how some areas of clearing show individual colonies. What mechanisms may allow for that growth within a...
