2. Determine the molarity of the NaOH solution in each trial. a. Trial 1 Molarity: b. Trial 2 Molarity: 3. Calculate the average molarity of the NaOH solution. 4. Label the volumetric flask containing the NaOH solution with the average molarity.

This question is incomplete

Explanation:

This question is incomplete as the actual values are not provided however you can solve the question yourself if you have the actual value using the formulas below.

The formula for Molarity is

Molarity = number of moles (n) ÷ volume (in dm³ or Litre)

If number of moles is not given, to calculate for number of moles

number of moles (n) = given mass of NaOH ÷ molar mass of NaOH

Please NOTE that the volume MUST be converted to dm³ (or litre) if not provided in dm³.

The unit for Molarity is mol/dm³ or mol/L or M (molar concentration).

Average molarity = (Trial 1 + Trial 2 + Trial 3)/ 3

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
