Final answer:
The density of an object with a mass of 49 kg and a volume of 14 liters is 3.5 kg/L.
Step-by-step explanation:
To calculate the density of an object, we use the formula density = mass/volume. Given that the object has a mass of 49 kg and a volume of 14 liters (which is equivalent to 14,000 cubic centimeters or 14,000 cm³ since 1 liter = 1,000 cm³), the density can be calculated as follows:
Density = Mass / Volume
Density = 49 kg / 14 L
Density = 3.5 kg/L
Therefore, the density of the object is 3.5 kilograms per liter (kg/L).
