Answer :
The mass of liquid mercury that can fill glass tube is 680.365 gm.
We know that ,
Volume of cylinder = π[tex]r^{2} h[/tex]
where r is the radius of cylinder and h is the height
Here diameter of glass tube is 16mm
Thus the radius r = 8 mm
= 0.8 cm
Volume of glass tube = π [tex]0.8^{2}[/tex][tex]*25[/tex] [tex]cm^{3}[/tex]
Density of mercury given is [tex]13.53gm/cm^{3}[/tex]
We know that
Density = Mass / Volume
∴ [tex]13.53gm/cm^{3}[/tex] = Mass/ π[tex]0.8*0.8 * 25[/tex]
Mass = 13.53 *π0.8*0.8*25
= 680.36 gm
