... P1V1 ‗ P2V2
P = pressure, and calculations can be done when P is in millimeters of Hg (mm),
kilopascals (kPa), or atmospheres (atm) as long as both pressures are in the same units.
Standard pressure is 760 mm, 101.32 kPa, or 1 atm.
T = temperature, and calculations can be done only when T is i ...
