Sol. 6. Standard atmospheric pressure is always pressure exerted by 76 cm Hg column = (76 × 13.6 × g) Dyne/cm2. If water is used in the barometer. Let h →height of water column. ∴h × ρw× g

Pressure is same for all points So, height of h2ocolumn*density of water*g=height of mercury column*density of mercury*gh=.76*13600/1000h=10.336m or 1033.6cm
