Answer:
The volume of the gas is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
v------> the volume of a gas in cubic centimeters
p-----> the pressure of the gas in liters per square centimeters
so

we have

substitute and solve for k

The equation is 
<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>
so
For
Find the value of v
substitute in the equation
