Answer:
The molecular formula of the metal oxide is CuO
Explanation:
Molar mass 79.545 g/m belongs to CuO
This is the reaction:
2Cu(s) + O₂(g) → 2CuO (s)
2 mol of Cu produce 2 mol of CuO
Molar mass Cu = 63.5 g/m
Mass / Molar mass = 1.56 g / 63.5 g/m →0.0245 m
0.0245 mol of Cu produce 0.0245 mole of CuO
Molar mass CuO = 79.545 g/m
Mol . Molar mass = mass
0.0245 m . 79.545 g/m = 1.95 g
