9. I Calculate the molar mass of Cu_(2)O 143g/mol 45g/mol 79.5g/mol 37g/mol Multiple Choice 10 points

To calculate the molar mass of , we need to find the atomic masses of copper (Cu) and oxygen (O) and then multiply the atomic mass of copper by 2 (since there are 2 copper atoms in the compound) and add the atomic mass of oxygen.The atomic mass of copper (Cu) is approximately 63.55 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol.So, the molar mass of is: Therefore, the correct answer is .
