Hm. Lemme see.
What is the answer?
never mind disregard this. I found the answer to be 45 degrees
The above answer is wrong. (84000-45000) is not 28000, it is 39,000. Therefore 39000/3 is 13000. M =13000.
calculate the work done when 50.0g of tin dissolves in excess acid at 1.00 atm and 25 degrees c.
S^2- + Cu^2+ = CuS(s) .0177g CuS / molar mass CuS= Moles of CuS Moles of CuS= Moles of Cu Moles Cu/ Initial volume= Molarity of Cu
it suppose to be (3/x)-1=7/(x-20)
i wrote it wrong the 1st time. this is the problem. solve: (3/x)-1=(7/x-20)
