Number of moles = 8.3 x 10⁻¹³
<h3>Further explanation </h3>The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
5 x 10¹¹ atoms of Silver :
Answer:
The mass percent of copper as element is the same.
Explanation:
First of all we need the reaction that is presented below:
→
The mass percent of copper (Cu) as element is the same because of during the reaction the element only transform its nature from copper carbonate () to copper oxide (
), the latter is a solid and will remain in the system.
On the other hand, you will note that the global percentage mass will be small because of the reaction produce () that is a gas and this one will escape for the system.
Have a great day!
