The volume of a gas with a pressure of 1.2 atm increases from 1.0 L to 4.0 L.What is the final pressure of the gas,assuming constant temperature?

According to Boyle's Law, pressure and volume have an inverse relationship at constant temperature. Therefore, if volume increases, pressure must decrease. Using the formula P1V1 = P2V2, we can solve for the final pressure:

P1V1 = P2V2 
(1.2 atm)(1.0 L) = P2(4.0 L) 
P2 = (1.2 atm)(1.0 L) / 4.0 L = 0.30 atm

Therefore, the final pressure of the gas is 0.30 atm.
