Final answer:
The mass of the liquid in the cubic container is 22.50 g.
Step-by-step explanation:
The mass of the liquid can be calculated using the formula:
Mass = Density x Volume
Given: Density = 0.180 g/cm³ and Volume = (Side length)³ = 5.00 cm x 5.00 cm x 5.00 cm = 125.00 cm³
Plugging in the values, we get: Mass = 0.180 g/cm³ x 125.00 cm³ = 22.50 g
