Measure the mass of an empty container 2. pour the desired liquid in to
this container and wait for it to settle. 3. measure the mass of the
container + liquid 4. subtract the empty container mass to find the
liquid's mass Note: some scales have a tare feature (it defines a weight
of zero), which you measure the container's mass, use the tare option,
and then pour the liquid and wait for it to settle. Also, when you use a
scale, in truth you measure weight. It then divides by the known
gravity field to find a "weight" in kilograms, which we accept to equal
the mass in kilograms. You only truly measure mass when using a balance.
It compares the torque on the balance arm of the object's weight to the
torque on the balance arm of a slide-able weight. A balance will record
the same mass in any gravitational field.</span>

The human heart has only 4 chambers. Left and right atria and left and right ventricles.
