An atom of neon has a mass of `3.35 xx 10^(-23) g`. how many atoms of neon are there in `20 g` of the gas ?

Explanation

To find out how many atoms of neon are present in 20 grams of the gas, we can follow these steps:

### Step 1: Identify the mass of one neon atom
The mass of one neon atom is given as \(3.35 \times 10^{-23}\) grams.

### Step 2: Calculate the number of atoms in 1 gram of neon
To find out how many atoms are in 1 gram of neon, we can use the formula:
