Hello, fellow NGUers (or whatever the term is for members of this fine site) I am asking for help for my high school Chemistry homework for building a bottle rocket using 2L bottles. The problem goes as follows:

Using the molar mass of hydrogen peroxide (~34.02 g/mol), calculate how many grams of hydrogen peroxide you will need for the production of your rocket fuel.
Additional Info:
Moles of Oxygen gas calculated- 30.912

How do I set this up? I originally set it up like:
x/30.912 = 34.02/1
However, I came to the answer of 1064.145 g of H2O2 (keep in mind this has to fit inside a 2L bottle). Going on from that, I need to find the total volume of H2O2 needed so I have to convert it from grams to mL then multiply it by 10 to get the total volume.

:| this is a forum.. For gaming... And you bring.. Chemistry?

haha
hey its under general discussion, plus this site is full of young school kids im sure one can help

I'm one of those but don't know jack shit about Chem lol yet at least. Poor kid probably got an F already

If it's not too late, Hydrogen wanna jump in here lol?

Sure why not, so first the problem is asking to calculate how many grams are in 34.02 g/moles of H2O2.

Step 1: Write down your moles at the side of a paper.

Step 2: Find your Molar Mass, and write down at the side as well.

Step 3: Multiply Moles with the Molar Mass.

ex: 34.02 g/mole x 34.0146 molar mass = 1157.180094 grams.

If the question is in a proportional question, then we would have to cross multiply, and divide. Not sure if he needed the proportion answer or just the calculation of the problem.

I wish I still got to do stoichiometry and conversion ratios in Chemistry. Just wait till you get to acid and base buffers and solubility and organic chemistry, that shit will be fun. I would have helped as I was really good with stoichiometry, but Hydro seems to have the right answer there for you, as hydrogen is 1.01g/mol and oxygen 16, so 34.02 is correct :p

Why not join a like.. School forum lol?



You should help me out

School Forum?! hang me now.



Specter, Chemistry is the easiest thing i'm ever learning lol. So acid and base buffers and solubility and organic chemistry should be ez pz :p

Lol no? You seem to be a problem solver for this type of stuff.. But uh if you do hang yourself.. Can I take your spot in admin? :kappa:
