- When 10 mL of water at 20oC is placed in an Ostwald viscometer, it takes 136.5 s for the liquid levelto drop from the first mark to the second. For 10 mL of hexane at 20oC in the same viscometer, thecorresponding time is 67.3 s. Find the viscosity of hexane at 20oC and 1 atm.(ηH2O=1.002 cP, dH2O= 0.998 g/cm3, dC6H14=0.659 g/cm3)10.
