CuFeS<span>2 chalcopyrite
M(</span>CuFeS<span>2)= 2*63.5+55.8+32*2= 246.8 kg/kmol
3710kg*1kmol/246.8 kg= 15.0 kmol </span>CuFeS2
in 15.0 kmol CuFeS2 is 15.0 kmol Cu
15.0 kmol Cu*63.5kg/1kmol=953 kg Cu
Explanation:
KOH + 2H2SO4 ======> 2K2SO4 + H20
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
Ex: Provides more molecular space within particles and energetic compounds
