Concept explainers
(a)
Interpretation:
The density of given substance in grams per milliliter is to be calculated.
Concept introduction:
The density is defined as the ratio of mass of a body to its volume. For solid bodies densities are usually expressed in the units of grams per cubic centimeter, for liquids in the units of grams per milliliter and for gases in units of grams per liter.
(b)
Interpretation:
The density of given substance in grams per milliliter is to be calculated.
Concept introduction:
The density is defined as the ratio of mass of a body to its volume. For solid bodies densities are usually expressed in the units of grams per cubic centimeter, for liquids in the units of grams per milliliter and for gases in units of grams per liter.
