Learn how to calculate density using a real-life example of a gold coin. Explore how mass and volume are related to determine the density in a straightforward and easy-to-understand manner.
Alright, imagine you have a shiny gold coin in your hand. Let's think about its weight and how much space it takes up. Now, don't worry about any big words, I'll make this super simple for you! Density is a way to say how heavy something is compared to how much room it needs. It's like saying how many toys you can fit in a tiny box!
First, we need to figure out the density of your gold coin. To do this, we divide its mass by its volume. In our case, the mass of the gold coin is 22.2 grams, and the volume is 1.11 cubic centimeters. Are you following along so far?
Now, here comes the fun part - the math! We take the mass (22.2 grams) and divide it by the volume (1.11 cubic centimeters). So, 22.2 รท 1.11 = 20.0. This means that the density of your gold coin is 20.0 grams per cubic centimeter. Simple, right?
Remember, we need to round our answer to the tenths place. In this case, the density of your gold coin is 20.0 grams per cubic centimeter. So, when we round it to the tenths place, it remains 20.0 grams per cubic centimeter. It's like saying your toy box can hold exactly 20 toys in one tiny space!
So, in a nutshell, the density of your gold coin is 20.0 grams per cubic centimeter. That means for every tiny amount of space it takes up, it's pretty heavy. Keep this simple concept in mind, and you'll be a little scientist in no time!
