Answer:
The answer is
<h2>2.71 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
volume of marble = 1564 cm³
1 kg = 1000 g
4.24 kg = 4240 g
mass = 4240 g
The density is
We have the final answer as
<h3>2.71 g/cm³</h3>
Hope this helps you
Answer:
volume
Explanation:
The volume of the two samples of water will be different because volume is the amount of space occupied by a body. It is dependent on the amount of materials it contains.
- The 50g sample will have a higher volume compared to the 10g sample.
- The boiling point and density are intensive properties and do not depend on the amount of matter present.
- Since both samples are from the same source, they will have the same color.
