If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?

This problem is a relationship between pressure and volume.
To solve for the volume we would use Boyle's Law, which is comparison of the inverse relationship between pressure and volume.

$(P_{i}) (V_{i}) = (P_{f}) (V_{f})$ $(P_i)(V_i) = (P_f)(V_f)$

Identifying our values and units
$(P_{i})$ $(P_i)$ = 1.1 atm
$(V_{i})$ $(V_i)$ = 4.0 L
$(P_{f})$ $(P_f)$ = 3.4 atm
$(V_{f})$ $(V_f)$ = x

We plug in equation
$(1.1 a t m) \frac{4.0 L}{3.4 a t m} = (x L)$ $(1.1 atm)(4.0 L)/(3.4 atm)=(x L)$

Rearrange algebraically to solve for x

$x L = \frac{(1.1 a t m) (4.0 L)}{3.4 a t m}$ $x L = ((1.1 atm)(4.0 L))/ (3.4 atm)$

We get value of 1.29 L.

I hope this was helpful.
