1. How many grams are in 1.7 x 10^23 particles of Cl2? 2. How many moles are in 3.28 x 10^23 atoms of NaCl? *

3. If I were to determine how many liters 26 grams of water is, what type of conversion would this be? *

A Mass --> Moles --> Particles
B Mass --> Moles --> Volume
C Volume --> Mass --> Moles
D Moles --> Mass --> Volume

1. 20.0 grams

2. 0.272 moles

3. B) Mass --> Moles --> Volume

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

or

or  

Putting in the values we get:

1.

Mass of

2.

3.

Volume of water =

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
