The new pressure is #6 \ "atm"#.

Explanation:

If the temperature and the number of moles are constant, we may use Boyle's law here, which states that

#Pprop1/V# or #P_1V_1=P_2V_2#.

Since we need to find the new pressure, we might as well rearrange the equation in terms of #P_2#.

So, we got:

#P_2=(P_1V_1)/V_2#

Plugging in our given values, we get

#P_2=(2 \ "atm"*3color(red)cancelcolor(black)"L")/(1color(red)cancelcolor(black)"L")#

#=6 \ "atm"#

The new pressure will equal to six atmospheric pressures.
