Answer:

The mass of 8.250 moles of Cu2O is 1180.5g

Explanation:

HOW TO CALCULATE MASS OF A SUBSTANCE:

  • The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass as follows:

Mass (g) = no. of moles (mol) × molar mass (g/mol)

  • Molar mass of copper (I) oxide (Cu2O) = 63.5(2) + 16 = 143.09 g/mol

Mass of Cu2O = 8.250 mol × 143.09 g/mol

Mass of Cu2O = 1180.5 g

Therefore, the mass of 8.250 moles of Cu2O is 1180.5 g.
