Density = ______or how heavy something is for its size -Units are g/mL or g/cm3 -The density of water is 1.0 g/mL or 1.0 g/cm3. -Remember that 1.0 g/mL = 1.0 g/cm3!</p><p>Mass = the amount of matter in an object; measured in g or kg What tool do you use to measure mass?</p><p>Volume = the amount of space an object takes up; measured in mL, L, or cm3 List 3 ways you can measure volume: 1. 2. 3.</p><p>If an object has a large mass and a small volume, then its density will be ______and the object would ______in water. For example, a shot put ball would be very dense because it has a large mass and small volume.</p><p>If an object has a small mass and a large volume , then its density will be ______and the object would ______in water. Which object, the paperclip or the Styrofoam piece, is more dense?</p><p>Calculating Density </p><p>D = M ÷ V MassM • • M = D x V</p><p>• • • • V = M ÷ D Density Volume D X V</p><p>Practice Problem #1: Bob has 50 grams of water in a cup. When he pours it into a graduated cylinder, he finds that the volume of that water is 50 mL. What is the density of water? Known(s) Unknown Tool (formula) Solution M = 50 g D = ? D = M ÷ V</p><p>V = 50 mL Name ______Date ______Period ______# ______</p><p>Practice Problem #2: What is the mass of alcohol that fills a 200 mL container and has a density of 0.789 g/mL? Known(s) Unknown Tool (formula) Solution V = 200 mL M = ? D = 0.789 g/mL</p><p>Pop Can Density Demo</p><p>Describe 5 similarities and 5 differences that you can observe about this demo.
