Here, a liquid's density is to be determined by a 1-cm diameter cylindrical hydrometer whose division marks are non visable. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the 'liquid x', and it is observed that the mark for water has risen 0.85 cm above the liquid–air interface. In this case, the height of the originalwater mark is 12.7 cm. As such, how would I determine the density of the liquid?
