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?

Question

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

i got 74.08 is that correct?

Answer 1

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.

Answer 2

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

Answer 3

thanks
