V = k/P, so
VP = k, a constant
so, you want V so that
2.2V = 20*16
By the way, L/cm^2 is not pressure. 1L = 1000cm^3, so L/cm^2 = cm
Pressure is force/area, as in N/m^2
I've never heard of this L/cm^2 unit. But then, I'm not a physicist...
The volume of a gas in cubic centimeters, V, varies inversely with the pressure of the gas in liters per square centimeter, p.
When the volume of the gas is 16 cm3, its pressure is 20 L/cm2. Find the volume of the gas when the pressure is 2.2 L/cm2.

What is an L ?? Perhaps a Newton??? if cm^2/then D for Dyne
anyway
v = k/p
16 cm^3 = k / 20L/cm^2
k = 16*20
v = 16*20/2.2 = 145 cm^3
anyway
v = k/p
16 cm^3 = k / 20L/cm^2
k = 16*20
v = 16*20/2.2 = 145 cm^3
so the answer would be v=145.45
