If vacuum techniques have reduced a gas to only 45 molecules/cm when the temperature is 293 K, what is the pressure in the gas?

Explanation

To find the pressure of a gas when the number of molecules is given, we can use the ideal gas law in the form of \( PV = nRT \). Here’s a step-by-step solution:

### Step 1: Identify the given values
- Number of molecules, \( N = 45 \) molecules/cm³
- Temperature, \( T = 293 \) K
- We need to convert the number of molecules into moles.

### Step 2: Convert molecules to moles
