Calculate these volumes.

Hello, everyone, this is Ricky. And today we're gonna be calculating a couple masses. So what is the mass of six cubic centimeters of mercury, which has a density of 13 point 5939 grand percent of acute remember row density. And also remember that density is equal to mass volume. So that means mass equals density, times volume. So if we plug in our numbers, multiply everything out, we get that Mercury has again a mass of 81 16 grand's. All right. Now do the exact same thing for octane were given a volume in milliliters and a density a 0.702 grams percent. You're cute. Notice differences in our in our volumes Centimeters Cube milliliters to me after first before we can do this Problem's convert, um, no leaders to send me to cute. And so we have one cubic centimeter is equivalent to one no leader just for quite an easy swap. Now we just plug and chug tore formula mass equals density. Employing what? You got a nice right time or density and we get a final mass of 17 16 grams of octave. I hope this video is helpful. I'll see you in the next
