What volume of pure O2(g), collected at 27°C and 746 torr, would be generated by decomposition of 114 g of a 50.0% by mass hydrogen peroxide solution? Ignore any water vapor that may be present.
Concentrated hydrogen peroxide solutions are explosively decomposed by traces of transition metal ions (such as Mn or Fe). 2 H2O2(aq) 2 H2O(l) + O2(g) What volume of pure O2(g), collected at 27.0C and 746 torr, would be generated by decomposition of 115 g of a 50.0% by mass hydrogen peroxide...
Here is the problem again
I am really having problems with this question. Please if someone could help me out I would greatly appreciate it. Thank you.
