Question

A gram of gold has the same _____ as a kilogram of gold.

A. mass
B. weight
C. density
D. volume

Answer 1

C. density

Step-by-step explanation:

The density of a substance is an intrinsec property of the substance. It can be calculated as the ratio between the mass (m) and the volume (V):

`d=(m)/(V)`

however, it does not depend on these two variables, instead it depends only on the chemical composition of the substance or of the element.

In this problem, we have a gram of gold and a kilogram of gold. The mass of the two samples is different (1 g vs. 1 kg), but the density is the same, because the substance is the same (gold), so the density does not change.
