Water can be separated into its elements according to the following equation by electrolysis. If 20.0 g of water is decomposed by this method, how much oxygen gas is produced? 2H2O(l) 2H2(g) O2(g)
Added by Alice E.
Step 1
The molar mass of hydrogen (H) is approximately 1 g/mol and the molar mass of oxygen (O) is approximately 16 g/mol. Therefore, the molar mass of water is (2*1) + 16 = 18 g/mol. Show more…
