When 429 mmhg of argon, 1.2 atm of neon, and 225 mmhg of helium are mixed, what is the total pressure?
Dmitry_Shevchenko [17]

The total pressure  1566 mm Hg.

Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.

The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.

Partial pressure of Argon = 429 mm Hg

Partial pressure of Neon = 1.2 atm

   ∵ 1 atm = 760 mm Hg

=> 1.2 atm = 1.2 * 760 mm Hg

                 = 912 mm Hg

Partial presser of He = 225 mm Hg

S0, Total pressure = Par + P ne + P he

                              =  ( 429 + 912 + 225 ) mm Hg

                              = 1566 mm Hg
