8 Note Boxes Needed. Density. Bit of Review. Box #1. Mass: the amount of matter in an object (how heavy) Volume: the amount of space an object takes up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass.
Once you have balanced the scale, you add up the amounts on each beam to find the total mass.
What would be the mass of the object measured in the picture?
_______ + ______ + _______ = ________ g
We will be using triple-beam balances to find the mass of various objects.
The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up.

overall less density!
D = mass = g or g
volume mL cm3
Note: 1 mL = 1 cm3
Osmium is a very dense metal. What is its
density in g/cm3 if 50.00 g of the metal occupies
a volume of 2.22cm3?
Find the density of 500 grams of a substance if its volume is 125 cm3?
The density of octane, a component of gasoline, is 0.702 g/mL. What is the mass of 875 mL of octane?
Salt Water Fresh Water
An object displaces an amount of water equal to its mass
A solid displaces water and that amount of displacement is equal to its volume (space taken up)!
What is the density (g/cm3) of 48 g of a metal if the metal raises the level of water in a graduated cylinder from 25 mL to 33 mL?
You have 3 metal samples. Which one will displace the greatest volume of water?
25 g Al
45 g of gold
75 g of Lead
Which diagram represents the liquid layers in the cylinder?
(K) Karo syrup (1.4 g/mL), (V) vegetable oil (0.91 g/mL,) (W) water (1.0 g/mL)
