The density of a 40 gram object with a volume of 20 milliliters is 2kg/L.
To calculate the density of an object, the following relationship between its mass and its volume is needed:
[tex]d = \frac{m}{v}[/tex]
In order to adapt to the norms of the international system, it is necessary to change the value of the unit of mass to kilograms and of volume to liters:
- Mass
[tex]1 g = 10^{-3}kg[/tex]
[tex]40 g = 40 \times 10^{-3} kg[/tex]
- Volume
[tex]1 mL = 10^{-3}L[/tex]
[tex]20 mL = 20\times 10^{-3}L[/tex]
Now, just apply the values in the given density formula:
[tex]d = \frac{40\times10^{-3}}{20\times10^{-3}}[/tex]
[tex]d = 2kg/L[/tex]
So, The density of a 40 gram object with a volume of 20 milliliters is 2kg/L.
