1.	If 1 mL of water contains 20 drops, what is the number of water molecules in the one drop of water? (A = Avogadro's number)
Answer» `(0.5)/(18)`A `0.05`A `(0.05)/(18)`A 0.5 A Solution :c) `therefore` 18 mL = 18G of WATER contains = `20 xx 18` drops = A molecules `therefore` 1 drop contians = (A)/(20 xx 18)` molecules = `(0.05A)/(18)` molecules
