4.41g of copper contains 0.069 moles
To solve this problem, we have to use mass-mole-molarmass relationship.
Number of Moles
This is the number of moles present in a given element, molecule or compound.
To calculate for this, we can apply the formula of number of moles which is
[tex]\text{ number of moles }=\frac{mass}{molarmass}[/tex]
The molar mass of copper (Cu) is given as 63.5g/mol
Let's substitute the values we have into the formula and solve.
[tex]\begin{gathered} \text{ number of moles}=\frac{mass}{molar\text{ mass}} \\ n=\frac{4.41}{63.5} \\ n=0.069\text{moles} \end{gathered}[/tex]
From the above calculations, 4.41g of copper contains 0.069 moles
