Question

Alai records data about making a mixture of salt and water.



Which best explains why Alai’s salt measurement is wrong?

It should be recorded in milligrams.
It should be recorded in millimeters.
It should be recorded in centiliters.
It should be recorded in centimeters.

Answer 1

It should be recorded in milligrams.

Reason: salt is a mass (amount of substance) so it should be recorded in mass units (grams or milligrams). Millimeters and centimeters are length units, and centiliters are a volume unit.
