The Formula
The Answer

Answer 1

Therefore, the density of the anthracite coal is approximately 5.2055 kilograms per liter.

Step-by-step explanation:

To find the density of the anthracite coal, we can use the formula:

Density = Mass / Volume

1. Start by identifying the variables:

- Mass of the anthracite coal: 1.516 kilograms

- Volume of the anthracite coal: 292 ml

2. Convert the volume from milliliters (ml) to liters (L), as the SI unit for volume is in liters. There are 1000 milliliters in one liter, so the volume is 292 ml / 1000 = 0.292 L.

3. Substitute the values into the formula:

Density = Mass / Volume

Density = 1.516 kilograms / 0.292 liters

4. Divide the mass by the volume to calculate the density:

Density = 5.2055 kilograms per liter
