chemistry was last year, but give me a minute and i'll see if i can remember.
*edit*
okay, you're going to have to think in terms of moles. you have one mole of Mg for every mole of Cu. once you have the molar weight, divide the 6.15 grams of Mg by it's molar weight. according to the chart i have with me, the molar weight of magnesium is 24.31 moles. that gives you 0.25298 moles. multiply that by the molar weight of copper (63.55 grams by my chart), and you get 16.07688 grams Cu. i think that's right, but (for your own good) double-check it. if you can't find another person, hit up a homework help websites somewhere. :D good luck.

chemistry
The capability to create mass distruction from simple formulas and chemical compounds and the realization of how to create premitive bombs and dangerous acids as well as how to roll the perfect weed. ideal for evil minds and hell for those who do not have the mental compacity. used to deturr blonds and morons from going into a learning Environment.
Chemistry Investingation 6.9
HS04 is a chemical compound so strong it can rip flesh from the teachers face....Try it u'r self!
PREDICTION: i beleive that the teacher will moan in agony as her face burns off
MATERIALS: dumb teacher
HSO4
100mL beaker
CONCLUSION: in conclusion my teacher now looks like a troll from lord of the rings

god, i just remembered about this thread, so thanx auslander, i managed to get the basics right ( i remembered things ) but i got the answer wrong, the bit where you put the number over the other number, i put them in the wrong place, other than that the teacher was happy. ¦¬D
