To prepare a solution of KCl, you weigh out 1.5672 (± 0.0003) g and dissolve it in a volumetric flask of 250.00 (±0.50) mL in volume. Express the molarity of the solution and its uncertainty with appropriate number of significant figures. (Formula mass of KCl is 74.551 ± 0.004 g/mol)

During a titration experiment, 50.00 mL of a certain solution needs to be transferred to an Erlenmeyer flask. To measure the volume, a student used a calibrated 10-mL pipette five times. If the pipette delivers an actual volume of 9.98 mL with an uncertainty of ±0.02 mL, what will be the uncertainty in the final volume?
A Grade A buret is used in a titration experiment. Calculate the uncertainty e of the volume delivered by a buret based on the data below. The typical uncertainty of a Grade A buret is e = 0.02 mL. initial reading = 0.25 mL final reading 10.22 mL The uncertainty of the volume delivered by the buret is ± mL. [Just write the numerical answer. Use, if necessary, a "cosmetic zero" when writing numbers less than 1; e.g. "0.1234", not ".1234"]
A researcher has developed a new analytical method to determine the percent by mass iron in solids. To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Are the results of the new method significantly different from the standard reference sample? (Hint: Use Confidence Interval)
What is the approximate uncertainty, or implied precision (±) of each measurement? Balance A: 15.746 Balance B: 15.75 Balance C: 15.7

Average and Uncertainty The molar mass of an unknown compound was determined in three repeat experiments. The molar masses obtained were 82.23, 81.55 and 82.00 g/mol. Assume the uncertainty in the average value to be the half range. Enter the average value and its uncertainty, both rounded to the appropriate number of digits (according to the Rules outlined in the Chem121 Lab Manual Appendix). g/mol
I don't understand the wording. The least significant digit means the last digit? 7.700 X 2.1 = 16.17 would the uncertainty be 0.01 ? 2.132 + 17 + 4.04 = 23.172 would the uncertainty be 0.001 ?
