In Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?
(8) Identify whether the following are examples of systematic or random error or are mistakes: a. Using an inaccurately calibrated buret. b. An uncertainty of 1 mg in the weight of your sample.∓ c. Overshooting the endpoint on your first sample, then hitting the endpoint on the remaining samples.d. Failing to let your volumetric pipet drain for a few seconds have most of the liquid has been delivered.

Please solve question correctly with correct number of significant figures and the correct absolute uncertainty. If you don't know for sure, please do not attempt. A solution of F- is prepared by dissolving 0.0961 + 0.0005 g NaF (molar mass = 41.989 + 0.001 g/mol) in 157.00 + 0.07 mL of water. Calculate the concentration of F in solution and its absolute uncertainty. Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations. 0.0146 0.002 [F] = M M Incorrect Incorrect
