Answer:
Use a balance and record the data in kilograms.
Explanation:
To answer this question, we need to know the difference between a balance and a scale.
A balance measures mass. In other words, a balance measures the amount of matter of an object. This measure is made by comparison with an object which mass is already known.
On the other hand, a scale measure weight, which is Netwons. Because a scale doesn't compare the unknown mass with another known mass. A scale measure the force due gravity exerted on an object.
Therefore, the right answer here is the first choice: Use a balance and record the data in kilograms.
