Question

The value of equivalent conductance for KCl, HCl & CH3COOK are 130.1, 379.4 & 95.6 Ω^-1 cm^2 mol^-1 respectively. The value of equivalent conductance of CH3COOH is

Answer 1

Pressure at a depth h below the surface of water=atmospheric pressure + pressure due to water column of height h.If atmospheric pressure is P, then 2P=P + hρg or hρg = PBut P=10 N cm–2=l0N/(10–2 m)2=105 N m–2Hence h=P/ρg=105/(103 × 9.8)=10.2 mThus a water column of height 10.2 m exerts a pressure equal to the atmospheric pressure.
