Question

Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the water that is displaced by the object, subtract the initial volume from the final volume. The volume of water displaced is equal to the volume of the solid object. Using a scale to measure the mass of the object, you can now calculate the density of the object as its mass divided by its volume. Use the simulation to explore this method. Part A Follow the steps provided in the simulation to add water to the graduated cylinder. Select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, find its volume, and calculate its density. To save time, you can approximate the initial mass of the solid to the nearest plusminus 1 g. For example, if you are asked to add 14.3 g of copper, add between 13g and 15g. Which of the following sets include two samples with an equal density? 15.2 g copper and 50.0 g copper 11.2 g gold and 14.9 g gold 20.2 silver and 20.2 g copper 15.4 g gold and 16.7 g silver
