Write the expression for Ksp Subtitute the numbers and solve. Post your work if you gt stuck.

How many kilograms of chalcopyrite needs to be mined to get 325g of pure Cu?

Anonymous · Answer

So my ksp expression is Ksp=(Pb2+)^1(CrO4)^1 Ksp=(1.40 x 10^-8)^1(1.40 x 10^-8)^1 Ksp=1.96 x 10^-16 Is this right?

Yes, that's ight. You know, of course, that the exponents 1 are not needed; however, there is nothing wrong with putting them there AND it serves to remind you each time to place an exponent. Many of my students through the years forgot the exponent. Good work!

Don't piggy back your question on another question. Usually those get ignored. When you repost as a separate question, show the equation you want to use to go from chalcopyrite to Cu.
