Learn how to calculate the density of a gold necklace step by step. Discover the concept of density with a simple example and grasp its significance in science and everyday life.
Let's learn about density with a fun example about a gold necklace! Density is a measure of how tightly packed the molecules of a substance are. To find the density of an object, we use the formula: Density = Mass / Volume.
In this case, we have a gold necklace with a volume of 2.15 cubic centimeters and a mass of 43.0 grams. First, we need to write down the formula: Density = Mass / Volume.
Now, let's plug in the numbers: Density = 43.0g / 2.15cm³. When we divide 43.0 by 2.15, we get the density of the gold necklace, which is approximately 20 grams per cubic centimeter (g/cm³).
Therefore, the density of the gold necklace is 20 grams per cubic centimeter. Remember, density tells us how much mass is packed into a certain volume of an object. So, in this case, the gold necklace is quite dense!
Understanding density helps us compare different materials and learn why some objects feel heavier or lighter than others of the same size. It's a cool concept that helps us understand the world around us!
