Question

How can I get kg with 4.41 moles of copper?

Answer 1

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

`\text{ number of moles }=(mass)/(molarmass)`

The molar mass of copper (Cu) is given as 63.5g/mol

Let's substitute the values we have into the formula and solve.

`\begin{gathered} \text{ number of moles}=\frac{mass}{molar\text{ mass}} \\ n=(4.41)/(63.5) \\ n=0.069\text{moles} \end{gathered}`

From the above calculations, 4.41g of copper contains 0.069 moles
