How much baking powder should you use to 100 pounds of flour?

You should not use baking powder in bread dough made from 100 pounds of flour. Baking powder is a chemical leavening agent used in baking, but for bread dough, you would typically use yeast as the leavening agent. Yeast is a microorganism that consumes the sugars in the dough and produces carbon dioxide gas, which causes the dough to rise. Baking powder contains baking soda, an alkaline compound that reacts with acidic ingredients to produce carbon dioxide, but it's not commonly used in bread dough because it can impart an unpleasant taste.
