Do not resize, remove, or add answer boxes.Experiment 1: Mass, Volume, and DensityIn-Lab Notebook (Results and Observations)During the lab period, use the answer box and fillable tables below to record your measurements, calculated values, and general observations. Entering data directly into Microsoft Excel is helpful and encouraged but please also enter data directly into the tables hereas well. Include a title for each table and units for each table entry, as appropriate. See notes and examples below.Note on Table Titles: The ACS states that each table must include a one phrase (or sentence) title that describes the contents of the table. The title should be understandable without reference to the text or, in this case, the lab manual.1Example of a Table Title: “Rate constants for substitution reaction A as a function of temperature.”Note on Units for Table Entries: For each entry in a table, units should be included, either in the column header or in a separate column (similar to how units are treated in Excel), unless thequantity is actually unitless. The ACS does not require a separate column for units in a table but is requested here to avoid confusion. Units in the tables below are in parentheses.Note on Observations: Using the answer box below, make note of observations as they occurduring the experiment. One to two sentences are sufficient for any major steps, e.g., “the volume increased noticeably when…”. In general, observations should not include measurements (i.e., numbers).Table 1.*Mass and volume of water .
