The atmospheric pressure is 76cm of hg(density of hg is 13.6gm/cc).the height of water column (density of water is 1 gm/cc)that can give same pressure is_____cm

The water column that will give the same pressure would be:

76 cm Hg x 13.6 g/cc Hg / 1.0 g/cc H2O = 1035.2 cm H2O.

Correction 103.36 cm H2O.

Correction 1033.6 cm H2O. I hate typing on this phone!
