if unlimited iron is available to react with 34.0g of copper (II) chloride, how many g of copper metal would be produced?
Here is a worked example, Follow the steps.
how do you know what the actual yield will be?!
The example gives theoretical yield and that's all you can calculate from the data you posted. If you have the percent yield you can determine actual yield by
actual yield = theor yield x (%yield/100) = ??; otherwise, it can be done only by performing the experiment and measuring the actual yield.
