Verified step by step guidance1
Understand that the International System of Units (SI) defines base units for fundamental physical quantities.
Recall that mass is a measure of the amount of matter in an object, and it has a specific SI base unit.
Identify the SI base unit for mass, which is the kilogram, symbolized as kg.
Note that the other options correspond to different physical quantities: second (time), meter (length), and mole (amount of substance).
Conclude that the correct SI unit used to measure mass is the kilogram.
