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.

Admin? What
I seen you have applied for staff, good luck! Nah, chemistry is simple shit to me, but when it comes to any type of math
i'm in 10th, but I don't even know what an improper fraction is ._.

Lmao in 10th as well, and I tend to call moderators or any type of staff admins, my mistake but thanks! I believe that's when it's flipped or the top is higher than the bottom lol

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
Lol I just started acid and base buffets and indicators and they're pretty easy, maybe because I'm good in chemistry too (that doesn't mean I enjoy it, I just find it easy lol).

Yeah they aren't terribly difficult, but the other stuff such as organic chem and solubility when you get into a million different K constants is when it really starts to suck haha.
