Answer 3

Calculating the Mass of 60 Liters of Kerosene

To calculate the mass of 60 liters of kerosene, we can use the given information about the mass of 15 liters of kerosene.

Given: - Mass of 15 liters of kerosene = 12 kg 300 g

Calculation

To find the mass of 60 liters of kerosene, we can use the following proportion:

15 liters is to 12 kg 300 g as 60 liters is to x (the unknown mass in kg and g).

Using the given information, we can set up the proportion and solve for x:

15 : 12 kg 300 g = 60 : x

Now, let's solve for x.

Solution

Using the given information and the proportion, we can calculate the mass of 60 liters of kerosene:

15 : 12 kg 300 g = 60 : x

By cross-multiplication: 15 * x = 60 * 12 kg 300 g

x = (60 * 12 kg 300 g) / 15

x = 4 * 12 kg 300 g

x = 48 kg 1200 g

Answer

The mass of 60 liters of kerosene is 48 kg 1200 g.
