Options

A. 1
B. 2
C. 1.5
D. 2.5

Explanation

To find the density of ozone relative to oxygen under the same temperature and pressure, we can follow these steps:

### Step 1: Understand the relationship between density, mass, and volume
Density (D) is defined as mass (m) divided by volume (V):
\[ D = \frac{m}{V} \]

### Step 2: Recognize that density is proportional to mass at constant volume
At constant temperature and pressure, the density of a gas is directly proportional to its molar mass (molecular weight). Therefore, if we know the molar masses of ozone and oxygen, we can compare their densities.

### Step 3: Identify the molar masses of ozone and oxygen
- The molar mass of ozone (O₃) is 48 g/mol.
- The molar mass of oxygen (O₂) is 32 g/mol.

### Step 4: Calculate the ratio of the molar masses
To find the relative density of ozone to oxygen, we can set up the following ratio:
\[ \text{Relative Density} = \frac{\text{Molar Mass of Ozone}}{\text{Molar Mass of Oxygen}} = \frac{48 \, \text{g/mol}}{32 \, \text{g/mol}} \]

### Step 5: Simplify the ratio
Calculating the above ratio gives:
\[ \text{Relative Density} = \frac{48}{32} = 1.5 \]

### Conclusion
Thus, the density of ozone relative to oxygen under the same temperature and pressure is 1.5.
