The three isomers of pentane have different structural formulas.
answer : D= m/v
Explanation:
all about density and mass and size of the molecules in a liquid and how close they are packed together
does it have multiple choice
Answer:
<h3>The answer is 2 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 48 g
volume = 24 cm³
We have

We have the final answer as
<h3>2 g/cm³</h3>
Hope this helps you
Okay so because of the difference in density a simple method for telling the difference between the two is to put a sample in a container with oil, because water has a higher density than the oil it would sink to the bottom but alcohol on the other hand is lighter than oil and would float on top of the oil.
However with this question I think that what you would do is use the ice to find out what the substance is, it would float on top of the liquid if it were water because the water is denser than ice but the ice would sink if it was alcohol because the alcohol is less dense than ice.
I hope this helps you, good luck : )
