Explanation:
A slow, continuous process is defined as gradualism that occurs at slow rate but at a steady pace.
For example, stripes of a tiger develop slowly and at a steady pace so that they can hide in tall grass represents gradualism.
Whereas punctuated equilibrium is a process in which there is sudden and frequent changes that results in the formation of new species.
For example, species living in a sea for thousand of years breed and die over there and suddenly when there is change in sea level than animals must adapt represents punctuated equilibrium.

Answer:
The correct answer is: the mass in grams of one mole of a substance
Explanation:
The molar mass of a given substance corresponds to the mass of one mole of this in grams. Corresponds to a physical property of the substance. Example: the molar mass of water (H20) is:
Molar mass H20 = (Mass H) x 2 + Mass 0 = 2 x 1 g + 16 g = 18 g / mol
