The image above represents mean bubble point.

To compute for the mean bubble point, one essential parameter is needed and the parameter is **Glass gas solubility parameter (x).**

The formula for calculating mean bubble point:

P_{b}^{*} = 10^{x}

Where:

P_{b}^{*} = Mean Bubble Point

x = Glass Gas Solubility Parameter

Let’s solve an example;

Given that the glass gas solubility parameter is 12. Find the mean bubble point?

This implies that;

x = Glass Gas Solubility Parameter = 12

P_{b}^{*} = 10^{x}

P_{b}^{*} = 10^{12}

P_{b}^{*} = 1000000000000

Therefore, the **Mean bubble point **is **1000000000000.**
