It depends on the planted and surviving population in the field, but the US average is around 30,000 plants per acre. Some growers are experimenting with higher populations of about 40,000 plants per acre, but it's not common yet.
There are around 72,800 kernels in a bushel which is supposed to weigh 56lb. Typical planting rates are from 28,000 to 40,000 kernels per acre; 28-35,000 is more typical though. So about 25lb per acre is a good estimate.
A 50# bag of seed with a seeding rate between 24,000-28,000 will cover 2.5 acres.
Mostly One per plant- the plant is actually capable of multiple ( as is often seen in the case of baby corn varieties) cobs.
The main contributing factors being soil quality+water availability and crowding of plants (spacing between them and spacing between rows.)
The more space you give (with good soil+fertiliser+water) the better the chances of the plant being able to sustain >1 cob per plant.
*****************
MOST corn has 2 ears per stalk.
The US nationwide average corn yields are:
Yields can vary quite a bit by state, location, and year. For example, the record high corn grain yield was just under 400 bushels per acre.
You mean how many cobs of corn on one stalk. That number varies with the cultivar and species of corn. The GMO corn typically has only one cob per plant, while other non-GMO varieties can have up to three or four cobs per plant.
Certain exotics (such as the kind that makes "baby corn" like you would find in a US restaurant salad bar) have been known to have as many as 18 ears on one plant, though this is an extreme example.
Most corn stalks have one to two ears of corn on them.

Most farmers in the U.S. plant field corn by the seed count, not by the bushel. However, since most farmers plant somewhere around 30,000 seeds per acre, you can figure the bushels thus: 30,000 seeds divide by 2,000 seeds per pound equals about 15 pounds divided by 56 pounds of corn per bushel equals about 1/4 bushel per acre. There are a great many factors, including seed germination percentage, which could change that figure.

Depends on a lot of factors- but the average yield of well cultivated corn is 160 bushels per acre. A bushel of shelled, dried corn is 56 lbs. That is 8960 pounds, or about 4.48 tons.
If you are asking how many acres 100 pounds of corn seed will plant, there are too many variables to answer this question. It depends on what population density a farmer wishes to plant and the number of seeds per pound. Farmers plant anywhere from 28,000 seeds per acre to as high as 40,000 seeds per acre, and seed counts can range from 1,250 seeds per pound to as high as 4,000 seeds per pound.
Corn takes between one to two gallons per plant on a weekly basis. An acre of corn take 350,000 gallons of water over the 100 day growing cycle.
The U.S. average yield for 2010 was 46.6 bushels/acre, 43.0 bu/a in 2011.
It depends on how long the rows are. For example, you can plant one row 14,520 feet long or you can plant 70 rows 207.5 feet long or you can plant 1,452 rows 10 feet long. They will each be one acre.
Somewhere in the 1,100 pound range.
An acre is a constant unit of measurement - an acre of anything is equal to an acre of anything else.
The average yield of corn per acre in Pennsylvania is approximately 150 bushels. The average soybean yield is 40 bushels per acre.
30,000
Generally speaking about 300 gallons per acre.
