+150 It's amazing to think that if we could take a hypothetical oxygen gas giant and somehow crash it into Saturn, we could get an almost infinite supply of pure water by dropping a lit matchstick onto the resulting planet, amirite?

The oxygen giant would be about half the size of Saturn for the reaction to work. We'd also me able to make a planet made of water, if gravity permits. I have no idea how much gravity water has.

Not Jupiter, because it's like our meat shield against asteroids.

False. Although the ratio of oxygen to hydrogen in a water molecule is 1:2, the size of our supposed oxygen giant would not be about half the size of Saturn. Oxygen atoms are much larger than Hydrogen atoms so even though the ratio wiuld remain 1:2, the oxygen giant would be much largerthan roughly half of Saturn.

Yeah, no. All gasses have one mole per cubic decimetre (litre) at RTP. Only the mass would be more. Go learn some chemistry before using the False meme.

But it wouldn't be at RTP.

It would be at the same temperature and pressure. All gasses also expand or contract at the same rate. The point is that when temperature is constant, all gasses occupy the same volume per mole, not that it's only at RTP specifically.

How many atoms are in a mole?

by Anonymous 11 years ago

A mole is a measure of atoms, molecules or whatever the base unit of the substance we're talking bout is, not the volume they occupy or the mass they have, so in one mole of any substance, mixture or compound, there are a total of about 6x10^23 atoms/molecules. That's about 600 sextillion atoms. A mole (1 mol) of hydrogen will be less massive than 1 mol of oxygen, but since they both have two atoms per molecule, the ration of atoms is the same. If you already knew what a mole is, that was for the benefit of people who don't. All gasses are 24 litres (24 dm^3) at room temperature and pressure (RTP) and expand at the same rate, so they are the same volume as each other at any temperature or pressure, so long as they are still gaseous.

if anyone is confused Saturn is made mostly of hydrogen. btw that would be awesome

You can't 'almost' have an infinite amount of something. That doesn't make sense.

Finite means ending. Infinite would be never ending. Our civilisation would collapse or we would go extinct before using up that many Earth masses of water, so we would end before the water, thus it doesn't have an end, thus it is infinite. 'Almost' because there is a small chance that we would end later.
