The
mass is 25 grams. Please label and put a box around the
solution.
Purpose: To calculate the apparent weight of a mass when immersed in water. Students will also have the opportunity to learn how to use calipers to accurately measure lenghs. Background: Archimedes discovered that he could find the density of an object by comparing it's weight o its apparent weight when immersed in water (see example 10-8 in he textbook). When mmersed, the buoyancy due to the...
