Answer:

19 L

Step-by-step explanation:

Given that the volume (V) varies inversely with the pressure (P) then the equation relating them is

V = $\frac{k}{P}$ ← k is the constant of variation

To find k use the condition V = 5 when P = 304

k = VP = 5 × 304 = 1520

V = $\frac{1520}{P}$ ← equation of variation

When P = 80, then

V = $\frac{1520}{80}$ = 19 L
