3 mol of copper metal

contains approximately 192.22 grams of copper.

To calculate the mass of 3 mol of copper metal, you need to know the molar mass of copper.

The molar mass of copper (Cu) is approximately 63.55 g/mol.

To find the mass, you can use the formula:

Mass = Number of moles x Molar mass

So, for 3 mol of copper metal:

Mass = 3 mol x 63.55 g/mol

Mass = 190.65 g

Therefore, the mass of 3 mol of copper metal is approximately 190.65 grams.
