Text Solution

AI Generated Solution

To find the number of water molecules in a drop of water with a volume of 0.04 mL, we can follow these steps: ### Step 1: Calculate the Mass of the Water Drop We know that density (d) is defined as mass (m) divided by volume (V). The formula can be rearranged to find mass: \[ m = d \times V \] ...
