Here is my problem,

The density of ethanol is 0.80g/mL. A) If 15 drops of ethanol from a medicine dropper weigh 0.60 grams, how many drops does it take for the dropper to dispense 1.0mL of ethanol? B) what is the volume , in mL, of 1 drop of ethanol? Use dimensional analysis

So I converted 0.60g to oz and got 0.021oz and then my oz to mL and got 0.63mL so 0.63mL would the volume of 1 drop, right? If that is right I am still having problems with part a
