Re: Avagadro's Number
Just like a dozen of something is equal to 12 of that object, 1 mole of anything is equal to 6.022 * 10^23 of that object. When you look at atomic masses on the periodic table, they tell you how the mass of 1 mole of that specific atom. For example, 6.022 * 10^23 carbon atoms would be 12.0107 grams...

Re: Culinary Chemistry
Something I recently learned was the difference between heat-safe and regular glass. Heat-safe glass (like the kind you can use oven, eg. Pyrex) is made of borosilicate glass, which has a low coefficient of thermal expansion and therefore is less likely to break at high temperatures. I think this i...
