Each lab will have you perform the experiment and collect data on the data sheet. The data sheet can be found in your lab manual for each experiment. Be aware of the significant figures you record on you data sheet as it will affect any subsequent calculations. Your values should be what you obtain while performing lab. Any given examples with values will be with mock values. Use of these values will almost assuredly give you nonsensical calculations.
data sheet guide
A. Sketch Lab Equipment
The following list of lab equipment have links to images that you can use to sketch.
B. Balance Use
Pay attention to the number of figures you recorded after the decimal place for (1) and (2). This will determine the number of significant figures you report for (3).
In the example given, the mass report in (3) will be calculated by the subtraction of (1) from (2). For subtraction, the least precise will dictate the number of decimal places reported. Thus, 3 digits were given for (3) after subtracting (2) and (1) since they both had 3 digits after the decimal place. For (4) and (5), these value should be recorded using the tare on the balance

C. Dispensing Liquids
Subtracting the beaker mass from the beaker and 6 mL of water will give you the mass of the 6 mL water transferred. This is repeated for each instrument and used to determine which was the most accurate method of transfer. Remember the number of significant figures recorded. Notice that 3 digits are recorded after the decimal for each instrument and therefore 3 digits are given for the mass of water for each instrument.
Pay attention to which instrument is used for (6) through (11). These are not labeled in the data sheet provided from the lab manual. Also keep in mind that space to record the mass of water transferred is not provided but will be needed in order to determine which instrument was the most accurate. It presented here to provide clarity.
