Question

How many mL of glacial acetic acid would you pipette to prepare a solution of 100 mL of 5 M acetic acid solution (hint: molarity of glacial acetic acid)

Answer 1

I think I remember the concentration of glacial acetic acid (which I will call HAc) to be 17 M. So use the dilution formula of
mL1 x M1 = mL2 x M2
mL1 x 17 = 100 x 5
solve for mL1. Pipet the amount calculated in mL1 into a 100 mL volumetric flask, add distilled water to the mark on the flask, stopper, mix thoroughly, label.
