Understanding Specific Gravity
Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water. Since the density of water is 1 g/mL, a specific gravity of 14.5 means the object is 14.5 times denser than water.
Calculations
1. Find the object's density:
- Specific gravity = Density of object / Density of water
- Density of object = Specific gravity * Density of water
- Density of object = 14.5 * 1 g/mL = 14.5 g/mL
2. Calculate the object's mass:
- Density = Mass / Volume
- Mass = Density * Volume
- Mass = 14.5 g/mL * 4 mL = 58 g
Answer: The mass of the object is 58 grams.
