Suggestions for Lab report “Topic 11”

1. Purpose

2. Procedure ( Brief description in point form)

3. Data collection and Processing

a) Data collection
Trial Water volume ± uncert cm3 Balance reading ± uncert
Empty cup 0.00 3.045
1 + 10.00 13.128
2 + 10.00 23.205
3 + 10.00 …

Table 1: Successive masses of cup and 10.00cm3 of water


b) Data processing
• Show formulas and calculation ( Sample calculation if repetitive)
• Tabulate results
V water ± uncert cm3 Mass of 10.00 cm3 portion ± uncertg Deviation │m – X │ ± uncertg
10.00 … …
10.00


Table 2: ……………

• Calculate the mean deviation “d”

• Test the results for precision

• Test the results for possible rejection of a measurement. If any of the measurements should be rejected, prepare a new table of results excluding the rejected data.
