Answer:
No, you need both mass and volume to determine its desity to see if it can float.
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
Answer:
-Physical properties possessed by all stars:
- They are made of gases such as hydrogen and helium.
- They shine very brightly due to interaction of hydrogen and helium at appropriate pressure and temperature.
- They contain iron in their cores which monitors the fusion reaction.
- They make energy through fusion between the gases present in the stars which are hydrogen and helium.
- They are not spherical in shape hence this physical property is false in terms physical properties of the stars.

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
<h3>What are liposomes?</h3>
Liposomes are vesicles which are made up of a lipid bilayer membrane.
Liposomes are important as delivery vehicles for substances such as drugs.
Ultrasonication is a method of liposomes preparation.
Solution of liposomes is dependent on the size.
The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.
Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
