A student was calibrating a 10-mL pipette which was guaranteed by manufacturers to deliver 10.00 ± 0.02 mL if used correctly. He measured the mass of water delivered by the pipette five times and obtained the masses shown on the right. The mean mass is 9.98714 g.
a What is the absolute uncertainty associated with this mean mass? (use 1/2 range)
b He used a conversion factor (1 g = 1.0021 mL)
to convert mass to volume.
What is the mean volume?

A solution of F− is prepared by dissolving 0.0986±0.0004 g NaF (molar mass = 41.989±0.001 g/mol ) in 162.00±0.06 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.

(12 pts.) The principal investigator (PI) for the laboratory you are doing research in has tasked with you to make 100 mL of an aqueous sodium phosphate (Na3PO4) solution with a formal concentration of 10.00 mM. Proceed through the following steps to quantify the concentration and uncertainty for the solution you produce. Note: for molar masses use the following values (Na = 22.98976928(2), P = 30.973762(2), O = 15.9994(4) g/mol) And propagate uncertainty for molar masses of compounds as standard...

Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...
