Aluminum metal reacts with a solution of copper (II) nitrate. If you want to produce #5.4 * 10^24# atoms of copper, how many moles of aluminum metal are needed?
1 Answer
atoms of copper.
Explanation:
First we should always have a balanced chemical equation for any reaction we are calculating.
The balanced chemical equation for the reaction of aluminum metal with a solution of copper (II) nitrate is as follows:
Secondly we should allways know the conversion between atoms and mols. 1 mol =
The copper has
=
=
As the coefficients (the numbers at the front of the compounds in the chemical equation) are different to each other, we must change the mols.
As
So the aluminium must be
atoms of copper.
