Question

The following apparatus shows three enclosed 0.500 L bulbs connected by stopcocks. Bulb X at 200°C and has a total pressure of 650 mmHg contains Br₂(g), I₂(g), and Cl₂(g). Bulb Y and Bulb Z are both empty and held at a temperature of 95.0°C and 25.0°C, respectively. Initially, the stopcocks are closed, and assume that the volume of the lines joining the bulbs is negligible.
When the stopcock between X and Y opened and was allowed to reach equilibrium, X and Y has a total pressure of 270 mmHg. Calculate the moles of I₂ present in the system.
