Title: What is 'parts' in mole
Post by: Nilsjeika on April 12, 2010, 03:40:20 PM

Hi,
I'm doing a school assignement with a friend about fireworks. We have found a site about how to make a sparkler, unfortunatily, it's in English, and we speak Dutch. We understand all of it, except for one thing, we need
300 parts of pottasiumchlorate and
60 part of aluminum fines, flitter, or granules (by the way, what are those?)
and another 60 parts of barium nitrate.
What are these in g (gram) or mole?
Please mail response to

or send a message to my forum account

Thanks very much

I think that mean in gr because "part" is used since long time ago before mole were known, as fireworks. It's like the "parts" when you are cooking: 1 part of oil each 3 parts of milk...

They must be grams, because it doesn't have any sense to think they're talking about taking 60 moles af aluminium, since that would be more than a Kg of metal...

By the way, pure aluminium is a metal, and metals for chemical use are not sold in "two-meters-long" bars as if you wanted it to construct a window, so they're sold in the form of fines or balls inside bottles or little "plastic containers" (I don't know how to say it in english now...).
