Question
Chapter 1.5, Problem 1.5.1SR
Interpretation Introduction
Interpretation:
The volume of water contained in the graduated cylinder should be expressed in proper significant numbers.
Concept introduction:
Significant figures: The digits having a meaning in a given number are called as significant figures.
Significant figures – calculation rules
- Significant figure is a non-zero number (8883.2 has five significant figures)
- Zeros placement in between non-zero number are significant figures (20006 has five significant figures).
- Zeros before the non-zero number are not significant number (0.00080009 has five significant figures).
- Zeros after the non-zero number are significant in case of that number contains decimal point (2.1000 has five significant figures).
- Zeros after the non-zero number may or may not be a significant figure in case of that number does not have a decimal point (100 may have 1, 2 or 3 significant figures). In this cases use scientific notation to avoid ambiguity.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how
hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is
др
defined as Br=-()=-(200²)T'
(a) You might wonder why there is a negative sign in this formula. What does it mean when
this quantity is positive and what does it mean when this quantity is negative?
(b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!)
(c) Explain under what conditions for the ideal gas the compressibility is higher or lower,
and why that makes sense.
19. (3 pts) in Chapter 7 we will see a reaction of halocyclohexanes that requires that the halogen occupy an axial position with
this in mind, would you expect cis-1-bromo-3-methylcyclohexane or trans-1-bromo-3-methylcyclohexane to be more
reactive in this reaction? Briefly explain your choice using structures to support your answer.
