Question

Water can decompose into H2 and O2 via electrolysis. How many moles of H2 could theoretically be obtained from 87.5 g of water. theoretical yeild=:________________ mol H2

Answer 1

2H₂O ==> 2H₂ + O₂

87.5 g.........? ..........

87.5 g H₂O x 1 mol H₂O/18 g x 2 mol H₂/2 mol H₂O = 4.86 moles H₂
