A glass bulb of volume 100 `cm^3` is connected by a narrow tube of negligible volume to another bulb of volume 300` cm^3`. The apparatus is filled with air at a pressure of 76 cm of mercury and a temperatureof `12^@`C, andthensealed. The smaller bulb is then immersedin melting ice whilst the larger bulb is placed in boiling water.Calculate the fraction of the total mass of air in the larger bulb, ignoring the expansion of the bulbs.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the System
We have two bulbs:
- Bulb 1 (smaller): Volume \( V_1 = 100 \, \text{cm}^3 \)
- Bulb 2 (larger): Volume \( V_2 = 300 \, \text{cm}^3 \)

The initial conditions are:
