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)#

Identifying our values and units
#(P_i)# = 1.1 atm
#(V_i)# = 4.0 L
#(P_f)# = 3.4 atm
#(V_f)# = x

We plug in equation
#(1.1 atm)(4.0 L)/(3.4 atm)=(x L)#

Rearrange algebraically to solve for x

# x L = ((1.1 atm)(4.0 L))/ (3.4 atm)#

We get value of 1.29 L.

I hope this was helpful.
