Question

Estimate: Press Reset. Select Atoms, and using the slider, start with 1.000 × 1023 atoms of sulfur. (Note that pressing Start puts atoms into the atom counter, not the jars.)

Is this amount more or less than one mole?

Place the jar underneath the counter. Was the jar completely filled?

How many moles do you have?

Answer 1

1) The amount is less than one mole, 2) The jar is not completely filled, 3) We have 0.166 moles of sulfur.

Step-by-step explanation:

We proceed to respond each question below:

1) Is this amount more or less than one mole?

According to the Avogadro's Number, one mole of an element contains about
`6.022* 10^(23)` atoms. Given that we have
`1.000* 10^(23)` atoms, then we conclude that this amount is less than one mole.

2) Place the jar underneath the counter. Was the jar completely filled?

Let suppose that the jar can contain up to a mole of sulfur. Then, we conclude that jar is not completely filled.

3) How many moles do you have?

The amount of moles is determined by dividing the current amount of atoms by Avogadro's Number:

`x = (1.000* 10^(23)\,atoms)/(6.022* 10^(23)\,(atoms)/(mole) )`

`x = (500)/(3011)\,mole`

We have 0.166 moles of sulfur.
