Use the equation 2cu+o2--> 2cuo, to find how many grams of copper react to produce 2.44 mol cuo.

The amount of copper reacted will be 154.94 g.

Explanation:

For the given chemical reaction:

By Stoichiometry of the reaction:

2 moles of copper oxide will be formed by 2 moles of copper metal.

So, 2.44 moles of copper oxide will be formed from of copper.

Now, to calculate the mass of copper, we use the equation:

Number of moles of copper = 2.44 moles

Molar mass of copper = 63.5 g/mol

Putting values in above equation, we get:

Hence, the amount of copper reacted will be 154.94 g.
