Question 1

1.

What is the concept of a mole used for?

Question 2

2.

How many atoms do you think are in a grain of sand?

Hint: (Try to make an educated guess, just like if you were trying to guess how many M&Ms were in the jar).

DO NOT GUESS the M&Ms!

Question 3

3.

Avogadro was alive to see his work proven correct.

True

False

Question 4

4.

The number of atoms present in a balloon at 1 atm and 0°C will vary depending on the type of gas.

True

False

Question 5

5.

How many particles can fit in a balloon at 0°C and 1 atm? Write out the WHOLE number (not in scientific notation!).

Question 6

6.

Gases take up a lot of space because

gas molecules are larger

gas molecules have high kinetic energy

gases are mostly empty space

gases have low attraction between molecules

Question 7

7.

What name did scientists give to 6.02 x 10^23?

Question 8

8.

What is the second name that was given to 602 sextillion?

Fyi...

Question 9

9.

What volume of water is 1 mole?

Question 10

10.

Explain how big a mole is using one of the three metaphors from the video.

Question 11

11.

Bonus:
Go to: http://www.vendian.org/envelope/dir2/lots_of_dots/million_dots.html

Scroll through a million dots. How long do you think it would take you to scroll through a look at 6.02 x 10^23 dots if they were zoomed to a level large enough to see each individual dot?

Question 12

12.

Bonus 2:
Go to: http://www.vendian.org/envelope/dir2/lots_of_dots/million_dots.html

Scroll through a million dots. How many times would you have to scroll 1 million dots in order to see 1 mole of dots?
(Give a precise answer please, scientific notation is okay.)

Question 18

1 kg (1000 grams) of sugar contains 2.9 moles of molecules. How much does 1 mole of sugar weigh?

Question 19

19.

Compare the weight of 1 mole of water to 1 mole of sugar. How many moles of water would it take to have an equal mass to 1 mole of sugar?

Question 20

20.

Why do you think 1 mole of water (H20) and 1 mole of sugar (C12H22O11) have such different masses?
