Question

1. lariyah is completing a lab in which she is required to identify an unknown substance. she records several observations and measurements of the substance. which of the following properties will be most helpful to sarah in making a correct identification?

a. density
b. mass
c. volume
d. weight

Explanation:

Density is a characteristic property of a substance. It is calculated as mass per unit volume ($
ho=\frac{m}{V}$). While mass, volume, and weight can vary depending on the amount of the substance or the gravitational field (in the case of weight), density remains constant for a pure substance under specific conditions (temperature and pressure). So, measuring density helps in identifying an unknown substance.

Answer:

A. density
