Question

Calculate the mass of oxygen in the copper oxide. The molar mass of copper is 63.55 g/mol, and the molar mass of oxygen is:

a) 16.00 g/mol
b) 32.00 g/mol
c) 63.55 g/mol
d) 79.55 g/mol

Answer 1

To calculate the mass of oxygen in copper oxide (CuO), we can use the molar mass of oxygen and the molar mass of CuO. The molar mass of oxygen is 16.00 g/mol, and the molar mass of CuO is 79.55 g/mol. By using the ratio of the molar masses, we can determine that the mass of oxygen in copper oxide is 16.00 g/mol.

Step-by-step explanation:

To calculate the mass of oxygen in copper oxide, we need to know the chemical formula of copper oxide. Assuming it is CuO, we can determine the molar mass of CuO by adding the molar masses of copper (63.55 g/mol) and oxygen (16.00 g/mol). So, the molar mass of CuO is 63.55 + 16.00 = 79.55 g/mol.

To calculate the mass of oxygen in copper oxide, we can use the ratio of the molar mass of oxygen to the molar mass of CuO. The molar mass of oxygen is 16.00 g/mol. Therefore, the mass of oxygen in 79.55 g/mol of CuO is (16.00 g/mol / 79.55 g/mol) * 79.55 g/mol = 16.00 g/mol. So, the mass of oxygen in copper oxide is 16.00 g/mol.
