Answer:
So with bigger space occupied a bigger density. In this case A) an iceberg made of ice has a bigger density. While lead would be the substance with a bigger density per gram.
Explanation:
Density is the level of compactness a specific substance has. In other words space, a specific substant occupies. Some substances have a bigger density than others. Because all off them have different chemical and physical compositions. The formula to calculate it is:
Density = mass of the substance/ volume
From this group
lead has a density of 11.342 gram per cubic centimeter
Ice has a density of 0.92 gram per cubic meter
Aluminum has a density of 2.7 gram per cubic meter
Water has a density of 1 gram per cubic meter.
So with bigger space occupied a bigger density. In this case, ice has a bigger density.
