The specific gravity of the liquid is 1.2

Specific gravity of a substance can be calculated using the formula

$Specific \ gravity = \frac{Density \ of \ substance}{Density \ of \ water}$

First, we will determine the density of the liquid

Density is given by the formula

$Density = \frac{Mass}{Volume}$

From the question,

The mass of the liquid = 1.5 lb

The volume occupied by the liquid = 0.15 gal

∴ The density of the liquid is

$Density = \frac{1.5}{0.15}$

Density of the liquid = 10 lb/gal

(NOTE: Density of water = 8.34 lb/gal)

∴ $Specific \ gravity \ of \ the \ liquid =\frac{10 \ lb/gal}{8.34 \ lb/gal}$

Specific gravity of the liquid = 1.199

Specific gravity of the liquid ≅ 1.2

Hence, the specific gravity of the liquid is 1.2
