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 = 0.717 ft^3=20,303.18 mL

1 ft^3 = 28316.847 mL

Density of the mercury = d=\frac{m}{v}=\frac{275330.344  g}{20,303.18 mL}

d = 13.56 g/mL

Specific gravity of substance = Density of substance ÷ Density of water

S.G=\frac{d}{1 g/mL}

Specific gravity of mercury :

S.G=\frac{13.56 g/mL}{1 g/mL}=13.56 (unit-less quantity)

Clearly, the acid is in deficiency ; i.e. it is the limiting reagent, because the equation above specifies that that 2 equiv of HCl are required for each equiv of metal.

So if
