Cu + 2 AgNO3 ----> Cu(NO3)2 + 2 Ag

Answered by bobpursley
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.

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