2. Place a cup or beaker onto the electronic balance and tare the
balance.
3. Measure 10 ml of the first standard solution into a graduated
cylinder. Pour the solution into the cup on the balance and record its
mass on Data Table 1.
4. Pour the contents of the cup on the balance back into the labeled
cup or beaker, rinse and dry the “measuring” cup.
5. Repeat steps 2 thorugh 4 for each of the standard solutions.
6. Choose four different fruit juices and place them in small, labeled
cups or beakers. Which one do you think will have the most sugar?
The least? Write these predictions in your science notebook.
7. Place the cup or beaker for measuring mass back onto the balance
and zero it.
8. Measure 10 ml of the first juice into a graduated cylinder. Pour it
into the cup on the balance and record its mass on Data Table 2.
9. Empty the cup on the balance back into your labeled cup or beaker,
rinse and dry the “measuring” cup.
10. Repeat steps 7 through 9 for each of the fruit juice samples.
11. Return the standard solutions to the containers indicated by your
teacher to be reused, or pour them down the sink if instructed to
