The label on a soft drink bottle gives the volume in two units: 2.0 L and 67.6 fl oz. Use this information to derive a conversion factor between the English and metric units. How many significant figures can you justify in your conversion factor?

Explanation:

The significant figures are determined by 2.0. It only has 2 places, so the answer to the last question is 2.

The English unit is 67.6 oz

The metric unit is 2 L

So there are 67.6 fl oz / 2 L = 33.8 fl oz / L

In other words 1 liter has 33.8 fl oz

But you only have 2 sig digs so the answer is actually 34 fl oz/L

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

the dissolution of polymer can be thermodynamically described in 2 steps.
