Mole problem?

mole: the chemistry unit [6.022 x 10^23]

we have to come up with these problems for chemistry where we have to show all of our calculations, explanations, a diagram and a graphic.

ex. A mole of M&M's would fill how many holes the size of Lake Erie? A mole of Mars candy bars placed end to end would reach from here to Mars and back how many times?

with that, i was thinking about doing something with jello and the ocean, like how many moles of jello could fill the pacific ocean [or all bodies of water]

can you please list either ideas that relate to mine and/or websites that i could look at to find more information?

thank you so much

whatever you pick, make sure of the following:

1) use a pure substance, like an element or compound (so you can determine moles).

2) know the volume of what space you are trying to fill.

3) you might have to know the density of the substance. But only maybe.

So pick some things where you know all three of these variables.

{and if you REALLY wanna blow their minds, pick a gas, like "how much oxygen to fill a (known) space", and use the equality that one mole = 22.4 liters in volume.

I enclose the instructions below for future problems you're going to soon have. Print them:

I just show to try to help you learn, as most people need help with these:

Too solve these types of problems, use the following general steps:
