During Reconstruction, many small white farmers, thrown into poverty by the war, entered into cotton production, a major change from prewar days when they concentrated on growing food for their own families. Out of the conflicts on the plantations, new systems of labor slowly emerged to take the place of slavery.
The density of an egg will vary slightly between each egg. To determine it exactly you will need to find its mass and its volume. Density is mass divided by volume. The average density of an egg is 1.031 g/cm 3 (grams per centimeter cubed) or 1.031g/ml (grams per milliliter). The density of water is 1 g/ml. Salt adds mass while adding very little volume so it is a good additive to make the density higher.
Eggs are classified by weight by the dozen. Because of this, there will be slight variations in the weights of eggs in every carton. A dozen extra-large eggs weigh 27 oz. (about 2-1/4 oz. each on average), a dozen large eggs weigh 24 oz. (about 2 ounces each), and a dozen medium eggs weighs 21 oz. (about 1-3/4 oz.
