Overview
In the decomposition reaction, 1 mole of water (MW = 18.015 g/mol) was produced for every mole of CuO (MW = 79.545 g/mol) produced. If 3.6 g of CuO was produced during the reaction, how many grams of water were released as water vapor? (number of moles = mass (g) / molar mass (g/mol)). Choose the closest answr.
0.82 g
b. 1.80 g
c. 3.98 g
d. 0.92 g
