CH202 In Lab 01 Reaction Stoichiometry (In-Lab) SCHNELL ZACHARY EUGENE CH202, section 005, Fall 2008 Instructor: weiming zheng TA Web Assign Current Score: 50 out of 50 Due: Tuesday, August 26, 2008 07:15 PM EDT Description Welcome to your first CH202 In-Lab Assignment. You will need to be careful about how many significant figures you report. Your CH201 instructor has likely covered significant figures. Below is a quick review. When multiplying or dividing values , the number of significant figures (sf) reported in the answer should be equal to the lowest number of significant figures in the calculational values. For example: 1.5 M x 10.4 mL = 15.6 mmol. 1.5 M has 2 sf. 10.4 has 3 sf. The answer should be reported to 2 sf. Therefore, the reported answer should be 16 mmol. When adding or subtracting values , the number of significant figures (sf) reported in the answer should be equal to the lowest common place value in the calculational values. For example: 16 mmol - 8.2 mmol = 7.8 mmol. However, 16 mmol is only reported to the one's place value.
