Answer:
Specific gravity of mercury is 13.56 and it is an unit-less quantity.
Explanation:
Mass of the mercury = m = 607.0 lb = 275330.344 g
1 lb = 453.592 g
Volume of the mercury = v = [tex]0.717 ft^3=20,303.18 mL[/tex]
[tex]1 ft^3 = 28316.847 mL[/tex]
Density of the mercury = d=[tex]\frac{m}{v}=\frac{275330.344 g}{20,303.18 mL}[/tex]
d = 13.56 g/mL
Specific gravity of substance = Density of substance ÷ Density of water
[tex]S.G=\frac{d}{1 g/mL}[/tex]
Specific gravity of mercury :
[tex]S.G=\frac{13.56 g/mL}{1 g/mL}=13.56[/tex] (unit-less quantity)
