c. zinc will be more than that of copper d. none of these​

Answer 1

Answer:

Density

Density is the amount of matter in a given unit of volume. It can be measured in grams per cubic centimeter (g/cm3). It is a measure of how tightly packed the atoms of a substance are. When we say that ice is less dense than water, we mean that the water molecules are more tightly packed when they are in the liquid state. The formula for determining density is

One always hears that muscle is denser that fat. This means that I can work out, not lose weight and still lose inches off my waist. This is because 1 pound of muscle will take up less space than 1 pound of fat.

Mass is typically measured in grams. Volume is typically measured in ml which is the same thing as cm3 (or cubic centimeters of cc. 1 ml = 1 cm3 = 1 cc)

The density of water is 1.00 g/ml. The density of some common elements are shown below:
