D
gram (g)
0 Comments
Verified step by step guidance1
Understand that the International System of Units (SI) defines seven base units, each corresponding to a fundamental physical quantity.
Recall that mass is one of these fundamental quantities, and the SI base unit for mass is specifically designated.
Note that while the gram (g) is a unit of mass, it is not the SI base unit; it is derived from the kilogram.
Recognize that the kilogram (kg) is the SI base unit for mass, defined by a fixed numerical value of the Planck constant.
Conclude that among the options given, the kilogram (kg) is the correct SI base unit for mass.
