Answer:
1.39 × 10⁴ g
Explanation:
Step 1: Given data
Density of gold (ρ): 19.3 g/cm³
Volume of the gold bar (V): 720 cm³
Step 2: Calculate the mass (m) of the gold bar
The density of a substance is equal to its mass divided by its volume. This is expressed through the following expression.
ρ = m/V
m = ρ × V
m = 19.3 g/cm³ × 720 cm³
m = 1.39 × 10⁴ g
The mass of the gold bar is 1.39 × 10⁴ g.
