To Find the Mass of Anything:
Mass is the
amount of matter in something.
The mass of the object
will be the sum of the three beams.
Read the triple beam
What is the object's
The basic unit of measure for mass is the

Let's find the mass of
47.0 mL of water.

the mass of the beaker with water.
3. Measure the mass of
the beaker without the water.
4. (SUBTRACT) The mass
of the water is the difference.
What is the mass of 47.0 mL?
Find the Volume of a Liquid
Scientists use a graduated
cylinder to measure the volume of something.
Remember volume is
the amount of space an object takes up.
Because the liquid
is curved, to read the volume correctly you must look at the
meniscus (the bottom of the curve).
Read the graduated
cylinder to the right.
What is the volume
of the liquid?
To find the volume of an Irregular
1. Fill the graduated cylinder
to 50.0 mL.
2. Drop the object in on an angle.
3. Subtract 50.0 mL from the new
1.0 milliliter = 1.0 cubic centimeter
What is the volume of
To find the Volume
formula Length x Width X Height. It doesn't
matter what you consider your length, width, or height as long
as you don't measure the SAME SIDE TWICE.
