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
