Ms. Sue or someone smart can you please help I don't understand 😖😔
Mrs. Sue died due to sickness. I came here looking for the answer too. The best answer I have is 49.98. I added 15.98g and 34g. I'm not sure if it's right but it's the best I got.
That question is flawed or there is a typo somewhere. 49.98 SHOULD BE the correct answer BUT if you start with 49.98 g H2O2 and decompose all of it you do NOT get 34.00 g H2O and 15.98 g O2. Starting with 49.98 g H2O2 will give you 26.46 g H2O and 23.52 g O2.
RIP Mrs. Sue. Fly High. Thank you for all the help.
I do need help :')
