In a pure semiconductor, the number of conduction electron is `6xx10^(19)` per cubic meter. How many holes are there in a sample of size 1 cm x 2 cm x 2mm ?

Explanation

To find the number of holes in a pure semiconductor sample, we can follow these steps:

### Step 1: Understand the relationship between conduction electrons and holes
In a pure semiconductor, the number of conduction electrons is equal to the number of holes. Therefore, if we know the number of conduction electrons, we can directly say that the number of holes is the same.

### Step 2: Calculate the volume of the sample
The dimensions of the sample are given as:
- Length = 1 cm = 0.01 m
