Quick Chem question (1 Viewer)

Hey, ive got this question on my chem hw that seems weird. Its not like a really hard question or anythin but my answer is huge. Wondering if any1 else gets the same as me.

Question- The overall process for the production of metallic copper from Chalcopyrite is summarised by the following-

2CuFeS2 (s) + 5O2 (g) + 2SiO2 (s) TO 2Cu (l) + 4So2 (g) + 2FeSiO3 (l)

-Calculate the mass of copper which could be extracted from 1 tonne (1000kg) of pure Chalcopyrite.

Using mole theory i end up getting 346245.82 g of Cu being extracted. Anyone else get this? I may have screwed up, theres no solutions.

i don't know...but i do know that both reactants and products need to have the same mass in grams

 

[Riviet]

Yep, I got a very similar answer, only off by about 250g, but that's because we probably used different values for the masses of the elements.

 

[pulsado]

Yeah i also got something very similar

 

[yoakim]

yep, me too. .

 

[kloudsurfer]

Yep, got the same answer as Rivet.
