Consider the titration of 100 mL of 0.50 M formic acid using 1 M NaOH. What volume of NaOH is required to reach the equivalence point? In a titration, how many milliliters of 0.23 mol/L NaOH(aq) must be added to 11 mL of 0.18 mol/L HI(aq...
First, with an average volume of 9.5 × 10-14 liter for a yeast cell [34], a typical nutrient concentration of 10 mmol l-1 translates into 5.72 × 108 molecules. Temporal random fluctuations scale as the square root of the number of molecules [35], and will be of the order of 0.004...
Assuming the whole adult brain (1400 g) is gray matter, oxygen consumption for the whole brain is 56 mls(O2)/1400 g tissue/min, which is 2.2 mmoles/1400 g/min. Converting mmoles of O2 to mls of metabolic water (conversion factor 18 μl/mmol), this results in an estimated production...

It should be noted that estimating the free chlorides is not easy because it relies on an estimation of the porosity, which we assume to be filled with a solution with a chloride concentration similar to sea water (i.e., 0.5 mol/L). The chloride concentration in the pore solution at a...
