<h3>Further explanation</h3>Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass
The unit of density can be expressed in g / cm³ or kg / m³
Density formula:
ρ = density
m = mass
v = volume
1 gal equal to = 3785.41 ml
then 17.0 gal = 17 x 3785.41 = 64351.97 ml Octane
grams Octane = ρ x ml
grams Octane = 0.692 g.ml x 64351.97
grams Octane = 44531.563
molar mass Octane (C₈H₁₈) = 114
mole Octane = grams : molar mass
mole Octane = 44531.563 : 114
mole Octane = 390.627
From the reaction
C₈H₁₈ + 25/2 O₂ ⇒ 8 CO₂ + 9H₂O
mole C₈H₁₈ : mole O₂ = 1 : 25/2
mole O₂ = 4882.846
grams O₂ = mole x molar mass
grams O₂ = 4882.846 x 32
grams O₂ = 156251.099

Assume 1 tsp is approximately can hold 5 mL liquid.
Given the dose of medicine = 1.5 tsp
Converting 1.5 tsp to mL:
= 7.5 mL
Given the specific gravity of the medicine = 1.23
That means density of the medicine with respect to water will be 1.23
As the density of water is 1 g/mL
We can take density of the medicine to be 1.23 g/mL
Calculating the mass of medicine in grams:
9.225 g medicine is present in one dose.
