A container has a volume of #18 L# and holds #9 mol# of gas. If the container is compressed such that its new volume is #12 L#, how many moles of gas must be released from the container to maintain a constant temperature and pressure?

Answer 1

#color(blue)(" 6 moles of gas must be released."#

Avogadro's law can be used to find the solution:

#v_1/n_1 = v_2/n_2#

The initial conditions are denoted by the number 1, and the final conditions are represented by the number 2.

Let's list the variables that we know and don't know.

#color(magenta)("Knowns:"# #V_1#= 18 L #V_2#= 12 L #n_1#= 9 mol
#color(blue)("Unknowns:"# #n_2#

To find the final number of moles, reorder the equation as follows:

#n_2=(V_2xxn_1)/V_1#

Enter the provided values to determine the total moles:

#n_2=(12 cancelLxx9mol)/(18\cancel"L")# = #6 mol#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
