| MikeHQ: Regarding number/amount, the basic rule is that if you can theoretically count it, you use the word number, otherwise you use amount. So you can have a large number of knick-knacks, but not an amount of knick-knacks (though this aspect of the rule is so often overlooked now that it's apt to be completely forgotten soon.) And you can have a large amount of water, but not a large number of water, because you can't count "water". However, you can have large number of ounces of water, or a large number of water molecules, since those are countable things. Even if it's only theoretically countable, such as the number of stars in the sky, you're still supposed to use "number". |
