This is a question for a rather odd purpose. I came across a working LEGO model of a Russian tank and I'm trying to model it using CAD software. It has a motorized system to elevate and lower the main cannon. This is where putting it into words might get weird:
It uses a small motor which...
Right, I caught that. It should be 34.016g. I ran the same calculations with that number, but to no avail.
There was also actually 6.666g of solution, but what I've tried with that number is still wrong.
Homework Statement
Calculate the number of moles of oxygen gas produced from the completely catalyzed decomposition of 6.60ml sample of a 3.5% solution of H2O2. The density of the 3.5% solution of H2O2 is 1.01 g/ml.
Homework Equations
2(H2O2) --> 2(H2O) + O2
p=m/v
