The volume of a drop of rain was found to be 0.448 ml at N.T.P. How many molecules of water and number of atoms of hydrogen are present in this drop ?

Explanation

To solve the problem of finding the number of water molecules and hydrogen atoms in a drop of rain with a volume of 0.448 ml at NTP, we will follow these steps:

### Step 1: Calculate the mass of the drop of rain
Given:
- Volume of the drop = 0.448 ml
- Density of water = 1 g/ml

Using the formula for mass:
