Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20∘C. A 2.500×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by...

Calculate and enter the molarity of your
three HCl standardization trials using the volume of standardized
NaOH solution required for each and the average molarity of the
NaOH solution from the standardization trials with KHP. You should
report 3 significant figures, e.g. 0.488 M.
I need to find the average molarity of my NaOH to solve this,
but I am unsure on how to solve for it. It had a concentration of
0.1 M. Thank you!
