Answer:

Approx. #3/4*L.#

Explanation:

#"Boyle's Law"# gives us the relationship #Pprop1/V# for constant #T#, and for constant amount of gas.

Thus #PV=k#. For constant temperature, and constant amount of gas, as pertains in this scenario, we write:

#P_1V_1=P_2V_2#

And thus #V_2=(P_1V_1)/(P_2)=(2.60*Lxx1.00*atm)/(3.50*atm)=??L#.

The best thing about using these simple experimental laws of proportionality is that we can persist with using intuitively easy units such as #"litres"# and #"atmospheres"#. It is intuitively obvious that the volume of a gas sample under compression should reduce.
