Answer :
Final answer:
The density of the irregular object is 19.3 g/mL.
It's calculated by dividing the mass of the object by the volume of the water it displaces.
Explanation:
The question is about calculating the density of an irregular object.
The formula to calculate the density of an object is the mass divided by the volume of the object.
- In this particular case, we know that the mass of the object is 38.6 grams.
- The volume of the object is identified by the amount of water the object displaces which is from 20 mL to 22 mL.
- Therefore, the volume of the object is the difference between these two values, which is 2 mL.
- Using the formula, we get the density as 38.6 grams divided by 2 mL, which equals 19.3 g/mL.
So, the density of the given irregular object is 19.3 g/mL.
