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.
