What is the pressure in a gas container that is connected to an open-end U-tube manometer if thepressure of the atmosphere is 752 torr and the level of mercury in the arm connected to thecontainer is 8.60 cm higher than the level of mercury open to the atmosphere

Answer:

The pressure in a gas container  is 839.44mmHg

Explanation:

Density of Mercury = 13.56g/cm³ = 13556kg/m³

[tex]P_{A} = P_{0} +[/tex]  hρg/ P₀

where, g= acceleration due to gravity, 10m/s²

h= height= 8.6cm = 0.086m

[tex]P_{A}[/tex]= hρg/ P₀

= 0.086 × 13556  × 10

= 11658.16 kgm/ m²s²

= 11658.16 N/m² = 11658.16pa

= 87.4434mmHg

where 1 torr = 1mmHg

[tex]P_{0}[/tex]= 752torr = 752mmHg

[tex]P_{A[/tex] = 752 + 87.4434

= 839.44mmHg
