the percent of Cu in copperIInitrate is 63.5/187= about 1/3.
There for, if you react 25g Cu, you should get 75g about of copperII nitrate. Your answer looks good.
What mass of copper(II) nitrate would be produced from the complete reaction of 25.1 g of copper, according to the chemical reaction shown below?
Cu + 2 AgNO3 ----> Cu(NO3)2 + 2 Ag
i got 74.08 is that correct?

Yes, but I would round the number to 74.1 since you are allowed three significant figures from the 25.1 number.
thanks
