This is a _very_ involved question, but the answers so far are basically correct - you will have 56 lbs of shell corn.
I've been selling corn for about 30 years, & I do both shelled & ear corn.
A bushel is a volume measurement. However, selling crops you always run across a scale & actually sell by weight.
So, the corn is tested & corrected to a 'proper' bushel which is 56 lbs at about 15% moisture (some want 14.5%, some go as high as 15.5%...) and it is measured for 'test weight' which can be as low as 42 or over 60. (This number is what your corn _actually_ weights per bu.)
Ear corn is assumed to be sold as if it were kernal corn, and there are aprox 16 lbs of corn cobs per bu of ear corn, so corn on the cob will weigh about 70 lbs per bu. But there is always 56 lbs (assumed or corrected to...) of corn per bu, whether it is ear corn or kernal corn.
The actual weight per bu of either can vary a lot by the quality & moisture content of the corn. You probably want to understand & apply those corrections if you are buying high moisture corn or larger volumes of it.
Kernal size is not an indicator, some of my heviest corn (test weight) was from tiny kernals. In a drought the large kernals may lead to low test weight, but in a good year the large kernals are heavier....
It's confusing, but corn is generally sold by weight, converted (by charts) to a 'perfect' bu of corn which is 15% moisture, 56lbs, occupying an exact volume. Doesn't matter if it's on the cob or not - just use different charts to convert to the 56 lb ideal.
