Which of these is an extensive property of a substance? a. color b. hardness c. malleability d. volume

Option (D) is the correct answer.

Explanation:

Properties which depend on the amount of matter present in the substance are known as extensive properties.

For example, mass, volume are extensive property.

Thus, we can conclude that out of the given options, volume is an extensive property.

Whereas color, hardness, and malleability does not depend on the amount of matter present in the substance. Hence, they are intensive properties and not extensive properties.

i think that the answer is c

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
