1. When a bracelet weighing 383 g in air is submerged in water, a scale measures a weight of 349 g. What is the density of the bracelet? Is the bracelet
made of pure gold or something else? Explain. (Use 1.00 g/cm'as the density
of water and 19.3 g/cm'as the density of pure gold.)

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?
