Answer 1

Answer:

0.149 moles

Explanation:

The problem is asking us to convert 9.49 grams of copper into moles. We can do that by using copper's molar mass:

• Molar mass of copper = 63.55 g/mol

Now we proceed to calculate the number of moles:

• 9.49 g ÷ 63.55 g/mol = 0.149 moles

There are 0.149 moles of copper in the wire.
