It is rinsed one last time with the solution to be measured because if there is water in the burret, then it could alter the results. Slightly, but it is still altering it.
Answer : The number of drops it takes from a dropper to dispense 1.0 ml of ethanol is, 20 drops
Solution : Given,
Density of ethanol = 0.80 g/ml
Mass of ethanol = 0.60 g
First we have to calculate the volume of ethanol.
Formula used : 


The volume of ethanol is, 0.75 ml
Now we have to calculate the number of drops it takes from a dropper to dispense 1 ml of ethanol.
As, the number of drops in 0.75 ml of ethanol = 15
So, the number of drops in 1.0 ml of ethanol = 
Therefore, the number of drops it takes from a dropper to dispense 1.0 ml of ethanol is, 20 drops
