Answer :
The volume of hydrochloric acid is approximately 0.785 cubic feet, which is closest to the option 1.27 ft³. The correct option is D.) 1.27 ft³.
The Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water. Given the specific gravity of hydrochloric acid (HCl) as 1.18, it means that the density of HCl is 1.18 times that of water. Using the formula:
Density = Specific Gravity × Density of Reference Substance
Density of HCl = 1.18 × 62.4 pounds/cubic feet = 73.632 pounds/cubic feet
To find the volume of HCl with a mass of 57.8 pounds:
Volume = Mass / Density = 57.8 pounds / 73.632 pounds/cubic feet ≈ 0.785 cubic feet
Therefore, the volume of hydrochloric acid is approximately 0.785 cubic feet, which is closest to the option 1.27 ft³. The correct option is D.) 1.27 ft³.
