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)
