Calculate the number of molecules in a drop of water weighing 0.05 g.
Added by George K.
Step 1
Given that 1 mole of water weighs 18 grams and contains 6.022 x 10^23 molecules, we can calculate the number of water molecules in 1 gram of water as: 1 gram / 18 grams/mole * 6.022 x 10^23 molecules/mole = 3.34 x 10^22 molecules Show more…
