Equal masses of `He, O_(2)` and `SO_(2)` are taken in a closed container. The ratio of the partial pressures of gases `He, O_(2)` and `SO_(2)` would be

Options

A. `1 : 2 : 8`
B. `8 : 16 : 1`
C. `16 : 8 : 1`
D. `16 : 2 : 1`

Explanation

To solve the problem of finding the ratio of the partial pressures of equal masses of Helium (He), Oxygen (O₂), and Sulfur Dioxide (SO₂) in a closed container, we can follow these steps:

### Step 1: Understand the relationship between partial pressure and number of moles
The partial pressure of a gas in a mixture is directly proportional to the number of moles of that gas. Therefore, we need to calculate the number of moles of each gas.

### Step 2: Define the mass of the gases
Let’s assume we have equal masses of each gas. For simplicity, we can assume the mass of each gas is 1 gram.
