Finding Density

Finding the Density of Regular and Irregular Objects

Volume of a Cube = Length3 Find the Mass of the Cube   D = Mass(g) / Volume(cm3)
Volume of a Block = L * W * H Find the Mass of the Block D = Mass(g) / Volume(cm3)
Volume of a Cylinder = pr2h Find the Mass of the Cylinder D = Mass(g) / Volume(cm3)
Measure 50mL in Graduated Cylinder Mass the 50mL and Cylinder Add 5 Chips
New V - Old V =  Chip's V New Mass - Old Mass = Chip's 5, 10, 15 & 20 Limestone Chips
Knowing the Limestone's Mass and Volume... Density Can Be Calculated:   D = m(g) / v(mL)
Plot Mass and Volume Limestone = 2.2g / mL Add 1g/mL  &  4g/mL to Graph
The Density is the slope of the lines.  4g/mL is steepest, 1g/mL is lowest and 2.2g/mL is between them.
