Answer 2

When we compare the weight of certain items, like bowling balls or ping pong balls, we can place one of each on a scale and simply read the weight. But what if our objects are too small to weight just one of? We might resort to weighing a set number of these small items, dividing the weight by that set number, and thus arrive at the weight of the one item. That is exactly what we have had to do to weigh an atom. Since atoms are incredibly small (so small in fact that we have not yet seen just one atom), we have had to use a set number. This number is Avogadro’s Number, 6.02 X 10 23. One dozen is a quantity unit of 12. One gross is a quantity unit of 144. One mole is defined as Avogadro’s number of atoms. Since matter (which atoms are) has mass and occupies space, a mole has mass and weighs something. Atoms come in different sizes and weights. Hydrogen is the smallest atom. One mole of hydrogen weighs one gram, therefore, the weight of one atom of hydrogen can be determined -- one hydrogen atom in fact weighs one atomic mass unit (amu)

Answer 3

Lab concept^^
Questions i need answered--->
How does the data presented above relate to the hypotheses you generated earlier in the lab?

Are any hypotheses disproved by your experiment?

Did your distilled water boil at 100 degrees C? If not, what might account for this?

An experimental control is a test that lacks the experimental variable. Was one of the solutions prepared in this lab a control? If so, which one?


In our experiment, you controlled one of the factors. Which one (temperature or NaCl concentration) was it


This factor was the independent variable that was controlled by you, the experimenter. The other variable was a consequence of changes you made. This is the dependent variable. It was a consequence of changes in the independent variable.

What factor (temperature or NaCl concentration) was the dependent variabl
