We know that #1# #"atmosphere"# pressure will support a column of mercury #760# #mm# #Hg# in length. The pressure is simply the fraction.

So #"Atmospheres of pressure"# #=# #"190 mm Hg"/("760 mm Hg" *(atm^-1))# #=# #19/76# #"atmospheres"#.

#=0.25atm#

we know pressure of 760 mm of Hg = 1 atm
So pressure of 190 mm of Hg #= 1 /760xx190atm=0.25atm#
