Today's assignment:
- Complete the Stoichiometry Puzzle
Remember, if you don't know what to do you can always ask!
Oh from my calculations you should be able to extract a whopping $4166.50 (yours might differ a little depending on how you rounded your numbers or what atomic masses you used).
You still need to show the calculations and the reactions you need to perform to get this though!
im having troubles with the worksheet you gave us. i cant figure out how much money i got out of the solution, i got 0.3292 out of .4938 with 0.1583 left.
ReplyDeleteThat's a good start. Figure out how to get the remaining Gold out next (you'll need another single replacement reaction).
ReplyDeleteOnce you have do that you will have a certain number of moles of Gold which you can then change into grams (remember that diagram I drew on the board a few weeks back?).
Once you have the gram mass, ask yourself how much is each gram worth and you should be able to do it from there.
Oh I should mention that you shouldn't get more gold than you have gold nitrate.
ReplyDeleteso should it be .3292X6.02X10power23 then times that answer by 394 to get the grams.
ReplyDeleteRemember you are trying to find the mass of that many moles of gold, not how many atoms of gold.
ReplyDeleteIf I remember the diagram correctly it went something like this:
Moles --> Mass you multiply the moles by the molar mass
Mass --> Moles you divide the mass by the molar mass
Moles --> # of atoms/molecules you multiply the moles by 6.02x10^23
# of atoms/molecules --> Moles you divide the # of atoms/molecules by 6.02x10^23
