Answer:
0.571moles
Explanation:
The Avogrado's number or constant denoted by NA will be used for this question.
The Avogrado's number = 6.022 × 10^23 particles, is contained in 1 mole of a substance.
To get the number of atom/particles in a substance, the formula: N= n × NA is used.
Where; N= Number of atoms in
substance
n= number of moles
NA= Avogadro's constant
Hence, to find the number of moles of copper equivalent to 3.44 × 10^23, we say: n= N / NA
That is, n = 3.44 × 10^23 / 6.022 × 10^23
= 0.5712
Therefore, 0.571 moles of Copper (Cu) is equivalent to 3.44 × 10^23 atoms of Copper.
