Give some reasons why the experimental weight of a cup of flour might differ from the standard weight
White flours have particles that differ in size, shape, and density. Particles have a tendency to pack. Experimental measurements and standard weights recorded when measuring flour can differ due to the amount of packing involved. If an individual firmly packs unsifted, spooned flour it will weigh more than its standard weight. The amount of air incorporated into the dry measuring cup also affects the differences in standard and experimental weight. Human error and individual measuring techniques make measurements less accurate and less precise. This will cause an experimental weight of flour to be more or less than the given standard weight. The weight may be different because of inconsistent scales or utensils.
