what is denser, 1 grams of gold or 1 kilograms of copper? why?
Gold is denser, in any amount, than copper. Density is independent of the amount of the sample. It is what is called an intensive property.

To determine which substance is denser, we need to compare their densities. The density of a substance represents how much mass is packed into a given volume.
To find the density of an object, we use the formula: density = mass/volume.
Let's calculate the densities of gold and copper first:
1. Gold:
Since we have 1 gram of gold, we need to determine its volume. However, we'll need the density of gold to find the volume. The density of gold is approximately 19.3 grams per cubic centimeter (g/cm³).
So, if we divide the mass (1 gram) by the density (19.3 g/cm³), we can find the volume of 1 gram of gold.
Volume = mass/density = 1 gram / 19.3 g/cm³
2. Copper:
Since we have 1 kilogram of copper, we need to determine its volume. Similarly, we need to find the density of copper to calculate the volume. The density of copper is approximately 8.96 grams per cubic centimeter (g/cm³).
To find the volume of 1 kilogram of copper, we first need to convert the mass to grams (1 kilogram = 1000 grams). Then we divide the mass (1000 grams) by the density (8.96 g/cm³).
Volume = mass/density = 1000 grams / 8.96 g/cm³
Now, to determine which substance is denser, we compare the volumes obtained for gold and copper. Whichever substance has a smaller volume will be denser.
By calculating the volumes, you will find that the volume of 1 gram of gold is smaller than the volume of 1 kilogram of copper. Therefore, gold is denser than copper.
Explanation:
We compared the densities of gold and copper by finding their volumes using the mass and density values. By comparing the volumes, we determined which substance was denser.
