Question

How many moles Of H2O will be produced from 42.0 g of H2O2?

Answer 1

`Molar{Mass} H_(2)O_(2) =2*16.0+2*1.0= 34.0 g/mol 42.0 g H_(2)O_(2)* (1 mol H_(2)O_(2))/(34.0 g H_(2)O_(2)) = 1.24 mol H_(2)O_(2) 2H_(2)O_(2) --\ \textgreater \ 2 H_(2)O +O_(2) \\2 mol ----2 mol (from// reaction) \\1.24 mol ---1.24 mol (from the problem) Answer: 1.24 mol H_(2)O.`
