Question

Calculate the moles of copper produced from the masses as recorded in the data table

Answer 1

0.0284moles

Explanations:

The formula for calculating the moles of an element is given as;

`moles=\frac{mass}{molar\text{ mass}}`

Determine the mass and molar mass of copper

`Mass\text{ of copper}=mass\text{ of copper}+filter\text{ paper}-mass\text{ of filter }paper`

Given the following parameters

Mass of copper+filter paper = 2.4581grams

Mass of filter paper = 0.6503grams

Substitute

`\begin{gathered} Mass\text{ of copper}=2.4581-0.6503 \\ Mass\text{ of copper}=1.8078g \end{gathered}`

Determine the moles of copper

`\begin{gathered} moles\text{ of copper}=(1.8078)/(63.546) \\ moles\text{ of copper}=0.0284moles \end{gathered}`

Hence the required moles of copper is 0.0284mol
