Pre-Lab - Density of Liquids (Virtual Lab)

How many decimal places should the balance be read to?  (Hint: You always estimate one place past what you know)

• 0.1 (tenths)

• Hundredths (0.01)

• Thousandths (0.001)

• Ten thousandths (0.0001)

Can you use the same mass for the EMPTY graduated cylinder for the entire lab?

• Yes, because we are using the same graduated cylinder for every trial.

• No.  That is crazy talk and I won't hear of it.

To determine the mass of water in the graduated cylinder you...(pick one)

• subtract.  The mass of the graduated cylinder and water - the mass of the empty graduated cylinder

• None of the above.  We do not need the mass in this lab.

• subtract.  The mass of the empty graduated cylinder - the mass of the  graduated cylinder and water

• pour the water directly on the triple beam balance.
