The missing value is 6!

Step-by-Step Explanation:

First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)

Now, we can write this as a function, where we can represent the missing value as 'x'.

In order to get the missing value, we must solve the equation.

Step 1: Simplify.

Step 2: Subtract 22 from both sides.

x is equal to 6, which means the missing volume of gas is 6!

-14 is the answer
