Help, help, help. CHEMISTRY

i need to do chenmistry homework and need to do this :-



the question is.

if 6.15g of Mg metal was added to excess Cu(II)SO solution, what mass of copper would be formed?

please can u help me, maybe auslander or someother intellegent dude or dudette ( my word for females )

**edit** can u show working, because i need to show how i got the answer

 

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. good luck.

 

c'mon, flip! don't you remember high school chemistry?

 

BWAHAHAHA! darth darth darth...no one had any questions about flourescent lamps and what one can grow in one's closet, given the right fertilizer!

darthnip
i found ye picture,this one was in front


and ye plants in back of the tomato plants,

 

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

 

Well, thecraigc, god bless ya'! I haven't seen any of that stuff since 1966 and didn't understand a damned word of it!

 

yeah it easy, i learned it about 2 years ago, just that we are now revising for exams we have in 3 weeks and i have only done 30 mins math studdying.

¦¬D
