Because oil is less dense than water, they will not mix. Density is the ratio of the mass of an object to its volume. In other words, density is the amount of stuff (atoms,molecules,etc.) in a fraction of matter.   How to Find Density                                          To find the density of an object, you first need to know the things mass and volume.Then, you divide the object’s mass by its volume to find the density. Mass is measured in grams (g), and volume is measured in cubic centimeters (cc), or centimeters cubed (cm3) . When you find the density after dividing, you must label your a...

Hobbies     One of my hobbies is playing ukulele. In the picture below, you’ll see my  ukulele. A ukulele is like a small guitar of origin in Hawaii in the 1900s.  There are different size ukes , like shown in the picture below.  There are also different parts of a ukulele , as shown below. To play the ukulele, I have a pick (shown below) that I use to play so I don’t hurt my fingers over time. There is also a tuner, that helps me tune my ukulele before I play so the sounds are played correctly and not off. (Shown below) .
