Your science teacher hands you a small container filled with an unknown liquid substance. He asks you to measure the mass of the fiquid. What lab equipment will you use and how will you calculate the mass of just the liquid? Be sure to describe the process you would follow step-by-step.
1.
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.
