A gas has a volume of 525 mL at 625 Torr. What would be the new volume if the pressure was change to 1.5 atm?

Answer:

Here, we use Boyle's law: at constant temperature, pressure is inversely proportional to volume.

Explanation:

#P prop 1/V# OR #PV = k#

So #P_1V_1 = P_2V_2# (how did I get this formula from the former?)

So #V_2 =(P_1V_1)/P_1# #=# #??#

#625# #cancel(mmHg) xx 525 mL# #xx# #1/(1520*cancel(mmHg))# #=# #?? mL#

Here I am perfectly free to use non-standard units of pressure and volume; Robert Boyle (possibly) used inches of mercury.
