Determine how many atoms of silver would be produced if 100 grams of copper reacts with an excess of silver nitrate? given the equation: cu + 2 agno3 -> cu(no3)2 + 2 ag avogadro's number: 6.02 x 1023

-

2 x 10 ²⁴ atoms of Ag rounded off to 1 significant figures.

Explanation: -

Mass of Cu = 100 g

Molar mass of Cu = 63.55 g / mol

Number of moles of Cu = 100 g / (63.55 g/mol)

= 1.574 mol of Cu

The balanced chemical equation for the reaction is

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2 Ag

From the balanced chemical equation we see

1 mol of Cu gives 2 moles of Ag

1.574 mol of Cu gives

= 3.148 mol of Ag

1 mole of Ag has 6.02 x 10 ²³ atoms of Ag according to Avogadro's Law.

3.148 mol of Ag has

= 18.95 x 10²³ atoms of Ag

= 2 x 10 ²⁴ atoms of Ag rounded off to 1 significant figures.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
