A chemical formula can be used to determine the makeup of a substance. It tells you what elements make up a particular substance, like H2O is the chemical formula of water.
In comparison with liquids and gases, solids are more dense. The answer is letter B. <span>The
solid has a more definite shape and volume. The particles are locked into
place. It cannot be further compressed due to the bond that exists between the
molecules. The kinetic energy of the molecules is close to none because the
molecules are so close and so compact with each other. </span>
Answer:
= 0.3 moles

Answer: As the density of a substance increases, the attraction among its particles increases.
Explanation:
Density of the substance is defined as mass present in per unit volume of the substance.
From the above expression , we can say that density varies inversely with the volume of the substance.
Decrease in volume means particles are coming closer that is attraction between particles is getting increased by which they will now occupy less volume. And with decrease in volume the density of the substance will get increase.
Hence, the correct answer is option (B)
