no
P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^
One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water. http://www.planete-tp.com/en/article.php3?id_article=221
The specific gravity of limestone concrete is 2.37. Therefore 5 gallons of concrete would weigh 94.8 pounds.
Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.
It weighs around 1500 kg/cum. and solid concrete blocks weigh around 1800 kg/cum minimum.
No, a 60 pound bag of cement does not weigh the same when it is turned into dried concrete. Once mixed with water and set, the weight of the dried concrete will be slightly more than the original weight of the bag of cement due to the water and other additives in the mixture.

This can vary do to the mixture of sand, stone, cement... but an approximate average would be 3000 lbs
Yes, concrete typically weighs more than sand because it is a mixture of cement, water, and aggregates (such as sand and gravel). The density of concrete is greater than that of sand due to the combination of these materials.
Lead has a higher density than concrete, so a 1"x1"x1" cube of concrete would weigh less than the same cube of lead.

how much does a gallon of concrete weigh
That depends on how much you have purchased.
It depends on the density of the material. Cubic yards is a measure of volume. Pounds is a measure of weight. For example, one cubic yard of feathers will weigh fewer pounds than one cubic yard of lead.

5 gallons of cement would weight 5 * the weight of 1 gallon
On average, 8 cubic feet of concrete can weigh around 4,000-4,500 pounds, depending on the density of the concrete mix.
