No.
That depends on how many grains the round is. If you find the number of grains and do this math you can get the number of ounces. Number of Grains = Y Y x 64.79 _________ = ounces 28349.5231
A 36 caliber round ball typically weighs around 80 grains or 5.2 grams.
Depends on the powder.

Sand grains become rounded through a process called abrasion, where they rub against each other or other surfaces. This constant friction wears down the sharp edges and corners, resulting in smoother, rounded shapes over time. The movement of water, wind, or ice can also contribute to the rounding of sand grains.
.223 inches in diameter, typically 45 to 55 grains for the .223 Remington, and 80 grains for the .223 Wylde.
There might have been silos used for storing grains.
Yes, pollen grains are typically small enough to be visible with a magnifying glass. They may appear as tiny, round or oval grains of varying colors and textures when viewed closely.

There are a lot of variables involved with the number of grains of powder in any given caliber round. Most importantly are the type of powder and the weight of the bullet. After that is the loader's preference as to the velocity of the round. For example, I load a 155 grain .40 caliber bullet using Ramshot Zip powder for a "light" velocity of about 1050 feet per second using 5.3 - 5.4 grains of powder.
