Studdy Solution
STEP 1
Assumptions1. The SI base unit of mass is what we are looking for. . The mass of a platinum-iridium cylinder kept at the BIPM is the reference for this unit.
STEP 2
We know that the SI base unit for mass is the kilogram. This is a standard unit of measurement in the International System of Units (SI).
STEP 3
The other options provided (meter, pound, second) are not SI base units for mass. The meter is a unit of length, the pound is a non-S unit of mass, and the second is a unit of time.
STEP 4
Therefore, the SI base unit of mass equal to the mass of a platinum-iridium cylinder kept at the BIPM is the kilogram.
The answer is A. kilogram.
