Concentration Solution and Dilution Lab Report

Help me study for my Biology class. I’m stuck and don’t understand.

Procedure

1. Gather the volumetric flask, distilled water, graduated pipet, pipet bulb, sugar, scale, glass beaker, cup (plastic or drinking), scissors, and a sheet of white paper.
2. Tare the digital scale by pressing the Φ/T button so that the scale reads 0.0 g.
3. Remove the stopper for the volumetric flask from the top of the flask.
4. Place the dry volumetric flask on the scale to determine its mass. Record the mass of the volumetric flask in Data Table 8.

Note: You will use the mass of the dry volumetric flask throughout the experiment.

1. Cut a small square of white paper, fold it in half and then in quarters, and place it on the scale.
2. Tare the scale by pressing the Φ/T button so that the scale reads 0.0 g with the paper on it. See Figure 16.
