Using the Ostwald viscometer, the time required for ethyl alcohol to flow from one point to another was 48 seconds and for water the time was 95 seconds at 25°C. The density of ethyl alcohol at 20°C is 0.77822 g/mL and at 30°C is 0.77097 g/mL and that of water at 25°C is 0.9972 g/mL. The viscosity of water at 25°C is 0.8904 cp. What is the density of ethyl alcohol at 25°C? What is the viscosity of ethyl alcohol in centipoise? What is the relative viscosity of ethyl alcohol?
